Abstract :
The high power transmitter active integrated phased array antenna and the rectenna array for the microwave wireless communication and power transmission are demonstrated at 5.8 GHz. The 4 W high power GaAs FET amplifier was developed for the transmitter antenna with the total power of 120 W. The average distance to the rover was 2.5 m. The active integrated phased array antenna with the beam steering function was operated with the 4-bit digital phase shifter by the thin LTCC substrate. In this array, the MSK modulation with the AB-class operation by the high power amplifier was adopted and obtained the BER of 10-6.
