Abstract

A 4 × 4 antenna array is designed, investigated and optimized at 5.8 GHz for Space-Based Solar Power (SBSP) applications. The array element is a coaxially fed microstrip patch antenna with edge chamfers for circular polarization. A parametric study is performed to optimize the antenna at 5.8 GHz with circular polarization. It is found that with a chamfer length of 2.97 mm, the patch antenna operates at 5.8 GHz with a magnitude of reflection coefficient, S₁₁, of -26 dB, a gain of 7.1 dBi, and an axial ratio of 2.95 dB. The element alignment and spacing is studied and it is found that with symmetrical patch alignment and element spacing of 0.68 λ 0, an array gain of 19.2 dBi and a radiation efficiency of 95% can be achieved. By using Friis formula, it is found that the SBSP system can deliver -45.58 dBm from a Low Earth Orbit Satellite at an altitude of 450 km with an EIRP of 66 dBW. In addition, the EIRP is used to calculate the incident electric filed of a circularly polarized plane wave and the simulation results show that the antenna array receives a power of approximately -55 dBm at 5.8 GHz.
