Abstract

In this letter, we present a method for improving the front-to-back ratio (FBR) of a broadcast antenna. The digitalization of terrestrial TV demands more efficient channel usage due to the reduction in TV bands after the switch-over. Thus, we designed an antenna with an FBR improved over -45dB as compared to the -20 to -25dB FBR range of existing antennas. We show experimentally that this antenna satisfies the required performance.
