• Two types of CPW-fed active antenna for television receivers, printedon thin dielectric film, are analyzednumerically and experimentally and their broadband operations are reported.The actual gain of the receiving active antenna is expressed in terms of the transducer power gain of the amplifier circuit and the effective length ofthe passive antenna. Between the feedpoint of the passive antenna element and the CPW, the silicon transistor 2SC2585 or 2SC3604 is integrated with a dipole antenna or loop antenna. The actual gains of a dipole antenna with 24cm length are more than 8dBd(relative gain to the standard half-wave dipole)at frequencies from 470 to 770 MHz fortelevision channels 13-62 in Japan. In the case of a loop antenna with a size of 25.8cm×12cm, actual gains of more than 3.5dBd are obtained for channels 1-12, from 90 to 222MHz, and more than 6.5dBd for channels 13-62, from 470to 770MHz.
