Overview
Designing antenna arrays with controlled beam patterns — synthesising element spacing, excitation amplitude, and phase distributions for pencil beams, shaped beams, null steering, and adaptive beamforming in radar, 5G mmWave, and satellite communication applications.
Deliverables
Key Aspects
Synthesising element excitation coefficients for target beam patterns using Dolph-Chebyshev, Taylor, and custom weighting — balancing mainlobe gain, sidelobe level, and null depth requirements.
Computing mutual coupling between array elements and correcting excitation coefficients for coupling effects — ensuring the embedded element patterns and active impedances match array synthesis assumptions.
Evaluating beam squint, gain roll-off, and impedance mismatch as the array beam is steered off broadside — defining the usable scan volume and identifying performance degradation mechanisms at wide scan angles.
Designing element spacing and array geometry to suppress grating lobes across the full operating band and scan volume, ensuring no unintended high-gain radiation directions within the application field of regard.
