Abstract	:	In this dissertation, three advanced system technologies are presented at mi-corwave and millimeter-wave frequecies.Firstly, an adaptive power controllable retrodirective array system is pre-sented. It is able to conserve battery power in an idle mode and wake up onlywhen it needs to operate, extending the array system's lifetime. One applicationof this technology is for use as wireless sensor servers which act as a relay pointbetween wireless sensors and remote data collectors. The proposed retrodirectivearray is fabricated and tested at 5.8-GHz and uses an integrated rectenna andan analog switch which controls a battery power source. When an RF signal isreceived by the antenna array,.
