Abstract :
This paper proposes an optimum design of a switched beam smart antenna system to improve the performance of wireless power transfer system to a MAV at 5.8 GHz. A planar 4x4 butler matrix was used as a beam-forming network to feed four linear patch antenna array in order to produce and steer four orthogonal beams in the desired directions (±39°, and ±15°). All the components of the proposed smart antenna system (antenna array, hybrid couplers, crossover, phase shifter) were designed, optimized and simulated with microstrip technology, on a FR4 substrate using ADS momentum software, which is based on the method of moments (MoM).
