I want to design a high gain antenna. Even amplitude excitation leads to side lobe levels no better than -13.26 dB. I want uneven amplitude excitation using chebyschev distribution. Also, cross polarization should be less than -40 in all phi cut.

hello, i have reviewed your project and understand you need a high-gain microstrip antenna design using uneven amplitude excitation based on Chebyshev distribution, with strict sidelobe and cross-polarization constraints. antenna design chebyshev array synthesis microstrip feed network i have experience in electromagnetic simulation and antenna array synthesis, including sidelobe control using amplitude tapering techniques and optimization of radiation patterns for performance constraints. what i can deliver: design of uneven amplitude excitation using Chebyshev distribution microstrip feed network design for targeted amplitude weighting sidelobe level optimization (improving beyond standard -13.26 dB limits) cross-polarization reduction techniques targeting < -40 dB across phi cuts MATLAB-based simulation and validation of radiation patterns array factor analysis and parameter tuning for gain optimization clear documentation of equations, design steps, and results i focus on antenna designs that are both theoretically correct and simulation-validated, ensuring results are reproducible and suitable for academic or practical RF applications. timeline: 3–7 days depending on array size and optimization requirements. i can start immediately. best regards

Hi, Understood — you need a Chebyshev-weighted microstrip array to push sidelobe levels well below the -13.26 dB limit of uniform excitation, while keeping cross-polarization under -40 dB in all phi cuts. My approach: 1. Compute Chebyshev amplitude coefficients for your target SLL (e.g. -20 to -30 dB) 2. Translate coefficients into a microstrip feed network — impedance transformers (Wilkinson or T-junction) sized to produce the correct power split per element 3. Validate full radiation pattern, HPBW, SLL, and cross-polarization in MATLAB (array factor + element pattern) 4. Iterate geometry until cross-pol < -40 dB across all phi cuts is confirmed A few quick questions before I start: • Operating frequency / band? • Number of elements and array geometry (linear or planar)? • Target SLL (e.g. -20 dB or -25 dB)? • Simulation only, or do you also need fabrication-ready dimensions? With those answers I can lock in the design and deliver within the timeline. Happy to begin immediately. Best, Ting-Jui Chou
