Microstrip antenna and rectifier for wireless power transfar at 94GHz

In this research, 94GHz microstrip antenna and rectifier was developed by MEMS technology for high power wireless power transfer system. To reduce the fabrication cost, a finline was also developed for RF power transmission from the wave guide to the microstrip line. As a result, the reflection loss was less than 1% and the antenna gain was 1.85 dBi. The rectifying efficiency was 38% with 105mW input power and 125 Ω DC load.
