Phased Array Active Loop Antenna for Television Receiver

Abstract

Two element phased array active loop antenna for the digital television receivers are analyzed and their broadband operations are reported. Between the feed point of the passive loop antenna element and the CPW, the silicon transistor 2SC3604 is integrated. When the size of a loop element is 25.8 cm × 12 cm and the distance between two loop elements is 30 cm, the actual gains of more than 13 dBd are obtained for 470 to 590 MHz. In this case, the front-to-back ratio of more than 8 dB are obtained.
