Antenna designtrabajos
My name is Troy. I have a small (for the moment) WISP in Medellin Colombia. I am using MikroTik routers exclusively in my network. I do have some antenna installs that are Ubuquiti but everything else is MikroTik. I need and an IT Engineer/Technician that is extremely familiar with WinBox to do the advanced programming on the routers. I would prefer someone that is "expert" level. I can do all the initial programming and get things up and running, but the finer points need someone smarter and more experienced than me. At this moment I need to have the routers checked out and the errors cleaned up. I need the web portal set up and the accounting and RADIUS programmed. I want a typical HotSpot set up done. I want the users to arrive at my website initially and be able to r...

Scope of Work: • Design a low-frequency (~15–30 Hz, target 22 Hz) EM transmitter • Optimize signal strength for underground detection • Develop efficient antenna/coil design suitable for pipeline use • Design low-power circuitry for long-duration operation • Integrate battery-powered system (alkaline) • Provide PCB design and component selection • Prototype recommendations (preferred) Key Requirements: • Frequency: ~22 Hz (very low frequency) • Detection range: 3–5 meters from the pipeline (measured from inside the pipe to the surface receiver) • Operation time: 5 days to 1 months (battery optimized) • Ru...
...that target I need both the hardware design and the accompanying firmware created with an obsessive focus on nano-amp sleep currents and efficient duty-cycling. Core capabilities • Data logging to internal flash or external EEPROM so records are retained between wake-ups. • LoRa communication only; no Bluetooth or Wi-Fi. The node will periodically wake, send an uplink, accept a downlink if present, and return to deep sleep. • Simple sensor block: one digital interrupt input (e.g., reed switch/pulse counter) plus one digital output that can drive an external load for a short, timed burst. Hardware scope – Complete schematic and BOM for the STM32WL-based board, including optimal power path, reverse-polarity and ESD protection, and a proven antenna...
...Summary of the Research This research focuses on designing a high-gain antenna for 5G communication at 36–38 GHz (millimeter-wave). Since 5G at these frequencies suffers from high signal loss, the study aims to improve signal strength using an efficient antenna design. The proposed solution is a compact stacked slot antenna, which provides: Wide bandwidth (34–44 GHz) Stable radiation pattern (consistent signal in all directions) Minimum gain of ~6 dBi (higher in arrays) To improve performance, the antenna is developed in three stages: Single antenna element – basic design and testing 1×2 array – increases gain by ~2–3 dB 1×4 array – further improves gain (~6 dB increase overall) The study pr...
...PCB layout, but I am looking for an experienced engineer to review, improve, and finalize the design for production. This is not a one-pass project. It will likely require back-and-forth discussion and iterative refinement to arrive at the correct final design. I want to be clear that I will be actively reviewing the work and asking questions as I go. I need someone who is comfortable with that process and open to collaboration. I do not want a situation where I feel hesitant to point out concerns or request changes. --- ### Critical Requirement (Very Important) This device must reliably SEND and RECEIVE wireless signals using ESP-NOW. Stable communication is essential to the product. The design must support: * consistent transmission and reception * minimal ...

Deliverables • Complete schematic and PCB layout (KiCad, Altium, or Eagle) • Verified footprints, stack-up and DRC reports • BOM with alternates that are currently in stock • Gerber/ODB++ files, pick-and-place and assembly drawings • Basic bring-up firmware that confirms Bluetooth advertising, LoRa transmission, GNSS fix and motion interrupt • Design notes on battery life c...
I need a fresh, distinctive logo that feels classic and timeless while still hinting at the modern mix of services our local antenna association offers— internet, streaming, linear TV, and mobile. I am picturing refined lines and balanced typography that will age well across print, web, and on-air idents. Core elements I definitely want to see explored are subtle antenna or signal motifs and tasteful technology cues (for example, a smart-device outline worked into the mark). Beyond that, I am happy for you to steer the creative direction—particularly with colour. Please choose a palette you believe best reinforces a trustworthy yet contemporary spirit; I’m open to anything from muted neutrals to a restrained splash of colour if it strengthens the concept.

...developing a smartwatch-style device and need a compact micropatch (microstrip patch) antenna that operates reliably at the 2.4 GHz Wi-Fi/Bluetooth band. The form factor has to suit a wearable, so low profile, light weight, and body-proximity tolerance are all important. What I need from you: • A complete electromagnetic design of the patch, dimensioned for common FR-4 or flexible substrates and tuned for 50 Ω matching at 2.4 GHz. • Full-wave simulation files (HFSS, CST, ADS, or similar) showing S11 below –10 dB, realistic radiation efficiency, and a clear far-field pattern when mounted on a small ground plane typical of a watch. • Fabrication-ready outputs—layout, Gerber/ODB++, and a concise design report explaining the stack-u...
...efficiently on both a small solar panel and a rechargeable battery pack. Wi-Fi connectivity is mandatory, and every part of the design has to prioritise ultra-low power consumption so the unit can sit in deep-sleep most of the day yet still wake to trigger a miniature solenoid valve on command. Power architecture The board should accept solar input (≈5-6 V) and seamlessly switch to a lithium cell when sunlight is unavailable. Please integrate an MPPT-style charge controller, battery protection, and a low-loss power-path so the ESP32-C6 always sees a stable 3 V3 rail. Current draw during sleep should stay well under 30 µA.

...an ESP32-based board and now need it translated into production-ready, two-layer Gerber files. Please work exclusively in KiCad so that I can review and maintain the project later. Follow standard IPC design rules throughout: clearances, trace widths, copper pours, silkscreen legibility, and all the usual checks that guarantee a smooth hand-off to any mainstream fab house. The board carries an ESP32 module, its accompanying power-management stage (regulators, protection, filtering), plus several sensors and small actuators. Placement should reflect good RF practice around the ESP32 antenna while keeping analog and noisy digital sections apart. I will supply: • the schematic (KiCad or PDF) • component datasheets and footprints when they are not in the KiCad...
I have a Python script that controls an antenna array and performs object detection with a basic Hamming-windowed FFT. While it works, the range resolution is still too coarse for my needs. I began experimenting with the MUSIC algorithm and even toyed with the idea of adding a continual-learning loop, but I would like a cleaner, expertly implemented solution—whether that is MUSIC, ESPRIT, a refined windowing strategy, or any other modern signal-processing method you can justify. Here is the current landscape: • Language & stack: Python with NumPy, SciPy and Matplotlib. • Key variable: signal-processing methods drive the entire detection chain, so any change must integrate cleanly with the existing pipeline. • Desired outcome: a measurable, demonstrable ...

I have a dual-band RF switch already drafted in Altium that lets one shared antenna handle both 433 MHz (primary) and 470 MHz LoRaWAN links. Before moving on to the board, I need fresh expert eyes on the schematic. You will receive the design as a PDF export. I’m most concerned about three areas: • Signal switching accuracy – verify the detector logic reliably senses the 470 MHz burst and that insertion loss, isolation, and TX/RX paths stay within spec on both bands. • Component placement – confirm the RF switch IC, matching network, SAW filters and biasing parts are arranged to minimise parasitics and avoid crosstalk. • Power management – check the regulator choices, decoupling strategy, and any GPIO level-shifting that could intr...

The design should include comprehensive protection mechanisms such as reverse polarity protection (preferably MOSFET-based), surge and transient protection (TVS), and fuse/PTC safety. Efficient power conversion is required using a buck converter for stepping down to 5V followed by low-noise regulation to 3.3V for the ESP32. The LiFePO₄ charging system must use a dedicated charger IC with appropriate voltage and current settings along with full battery protection features. The ESP32 section should follow best practices including proper decoupling, reset and boot circuitry, and strict antenna layout guidelines with no copper or ground under the antenna region. The board must include an internal USB T...
