The 4×4 high power active integrated phased array antenna operating at 5.8 GHz for wireless information and power transmission

摘要

The AIPAA with high power amplifier and the heat pipe was demonstrated. The AIPAA consists of the circular patch, the high power FET, the 4-bit digital phase shifter, the DC regulator and the heat pipe cooling system. For the functions of WIPT, the power transmission with 800mW output from each array element in the 4×4 AIPAA was achieved and the BER of 10−6 was kept with MSK with 9 Mbps. The beam steering was also carried out within +/− 23 degrees. WIPT to the rover in the moon are expected to be one of the promising space applications.
