Antenna Design Jobs

Hi, here is the complete project Objective Design and simulate a compact microstrip patch antenna Target specifications: - Frequency: 2.45 GHz (ISM band - Size: < 15-20 mm (very compact - Thickness (substrate): < 0.8-1 mm - Type: Miniaturized Simulation requirements: - Achieve S11 < -15 to -20 dB at ~2.45 GHz - Impedance matching to 50 ohms - single clear resonance (no multiple unwanted dips Deliverables: - Final CST project file (.cst - S11 plot (1-5 GHz range - Timeline: - Need completion within few hours (urgent Please let me know once you review this and if we can proceed, I'lI confirm immediately. Thank you.

I need a production-ready circuit and compact PCB built around the ESP32-C6 for an IoT device that must run 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.

I need a matched transmitter-receiver pair built around a 200 kHz carrier that can cover at least 40 m in open air and recognise simple OOK (On-Off Keying) pulses reliably. The intended application is “Radio Frequency RF”, so there is no higher-level protocol to worry about; raw, clean carrier switching will do the job. Everything will be mounted and operated outdoors, so the design must tolerate ambient temperature swings, sunlight and occasional moisture without detuning or loss of sensitivity. Both TX and Rx are separate not transceiver and battery powered with minimum 2 days running time. What I am looking for • Circuit-level design of both the low-power transmitter and the super-regen/ super-het (designer’s choice) receiver, including complete schematics, PCB...

I need a skilled Ansys HFSS user to run full-wave simulations on an antenna design and provide clear Return Loss (S11) results. This is a simulation-only assignment—no fabrication or physical testing for now. What I will share • Geometry or sketches of the antenna and the target frequency band. • Any material data or performance goals I already have. What I need back • The HFSS project file (.aedt) with all boundaries, excitations, and mesh settings correctly defined. • A PDF or image plot of S11 versus frequency that clearly shows the return-loss performance across the band. • A brief note (one page is fine) explaining solver settings, boundary conditions, and any tuning steps you took. At the moment, the exact antenna style is open; experience ...
