Project Description: I am looking for an experienced RF/Antenna Design freelancer to design and simulate a flexible wearable antenna using ANSYS HFSS for my final year project. Scope of Work: Design of a flexible microstrip/patch antenna for 5G (Sub-6 GHz, e.g., 3.3–3.8 GHz) and/or IoT band Selection and modeling of appropriate flexible substrate material (e.g., Polyimide, Rogers RT/duroid, textile substrate) Optimization of antenna parameters (length, width, feed position, ground structure, etc.) Simulation and analysis of key parameters: S11 (Return Loss ≤ -10 dB) VSWR Gain and Directivity Radiation Pattern (2D & 3D) Bandwidth Radiation Efficiency Bending analysis to evaluate performance under curvature (wearable condition) Parametric study and comparison with provided refe...

I need a focused research effort that looks at satellite-communication antennas from three angles at once: maximising signal strength and quality, mapping frequency-band usage, and refining antenna design and materials. The outcome should give me clear, data-backed guidance I can hand straight to my hardware team. Scope You will survey current literature and patents, run electromagnetic simulations (HFSS, CST, FEKO or similar), and translate the findings into practical design recommendations. Emphasis is on L-, S- or Ku-band performance; however, if your analysis uncovers a better-suited band, flag it and justify the choice. Deliverables • Concise comparative report (PDF) • Simulation files with setup notes • Performance charts showing gain, VSWR, efficiency and li...

I’m kicking off a multi-phase R&D effort devoted to the design and development of cutting-edge microstrip antennas. The overarching targets are straightforward: boost usable bandwidth while simultaneously lifting signal strength, all without compromising the core advantages of printed technology. Phase by phase, I’ll be iterating from theoretical models through to lab-verified prototypes. You’ll take the lead on concept generation, electromagnetic simulation (HFSS, CST or an equivalent full-wave solver), layout refinement, and hand-over for fabrication. Once hardware comes back, we’ll compare measured S-parameters and radiation patterns against the simulated baseline, fine-tune, and document lessons learned for the next spin. Key deliverables • Simulation...

I need a compact, production-ready circuit that brings reliable wireless communication to a new consumer-electronics device. The work begins with schematic capture and component selection, moves through PCB layout, and finishes with ready-to-manufacture Gerbers, a complete BOM, and clear test guidelines. The radio link is the heart of the design, so careful RF layout, antenna matching, and regulatory-compliant power levels are essential. Bluetooth LE is my preferred protocol, though I am open to Wi-Fi or other 2.4 GHz solutions if you can demonstrate lower cost or better battery life without sacrificing performance. Please plan on: • Delivering editable design files in Altium, KiCad, or Eagle, plus PDFs for quick review • Calling out any critical components with long le...

I already have a working ESP32 design in KiCad and need it brought to its final, production-ready form for a commercial product that must clear CE. The job centres on three key changes: swapping the Micro-USB for a USB-C connector, integrating a Li-Po charging IC, and tweaking the board outline and component placement so everything fits a new enclosure while preserving optimal antenna clearance, decoupling, and thermal performance. Please keep manufacturing constraints in mind and pass every KiCad DRC before delivery. Timeline is tight three days from award so I’m looking for someone who can move quickly yet meticulously. Deliverables • Updated KiCad project (schematic and PCB) • Fabrication package: Gerbers, drill files, BOM, and pick-and-place (CPL) ready for PCB...
