An active loop antenna for television receiver is presented and its broadband operation is reported. This antenna is fabricated on a thin dielectric film by using the photoetching techniques. A coplanar waveguide (CPW) is printed as a transmission line on the film. The GaAs FET FHC30LG is integrated between the feed point of loop and the CPW. Actual gains more than 9dBd (relative values to the halfwave dipole antenna) are obtained at the frequencies for television channels 4-12 from 170 to 222MHz and channels 13-62 from 470-770MHz in Japan.
