A Compact mmWave Butler Matrix for Wireless Power Transfer Conference Paper uri icon


  • A compact $4 imes 4$ butler matrix at 30 GHz is designed, fabricated and measured for wireless power transfer applications in microstrip configuration. The 90hybrid coupler is designed with two cross slots of different lengths. The crossover is realized using a ring and cross junction. The coupler and crossover are designed and analyzed. The butler matrix is verified by both the simulated and measured results.
