mmWave Microstrip Antenna Design

I need a compact, high-performance microstrip antenna engineered specifically for satellite communication in the mmWave region. The goal is to move from concept through full-wave simulation to fabrication-ready files while meeting tight performance targets on gain, bandwidth, and axial ratio.

Scope of work
• Electromagnetic modelling and optimisation in a recognised solver such as HFSS, CST, or similar, covering the exact mmWave band that satellite links typically occupy.
• Substrate selection with justifications (εr, loss tangent, availability).
• Impedance matching network design to maintain ≤-10 dB return loss across the operating band.
• Radiation pattern validation for both boresight gain and sidelobe levels suitable for satellite uplink/downlink links.
• Detailed mechanical drawing and Gerber files prepared for PCB fabrication.
• Concise report summarising methodology, simulation plots, and expected real-world performance.

Acceptance criteria
1. Simulated S11 ≤-10 dB across the agreed mmWave band.
2. Realised gain meets or exceeds the value defined during kick-off (to be finalised together).
3. Circular or linear polarisation purity better than 20 dB (as required for the link).
4. Complete transferable project folder containing source files, scripts, and drawings.

Please factor in a short review cycle for tweaks after the first simulation run. All intellectual property and native files transfer to me at hand-off.
