Abstract

High-definition television (HD-TV) is available via satellite broadcast and terrestrial HD-TV services. However, antennas that can receive HD-TV signals using different carrier waves (i.e., X band and UHF band) have not yet been designed. Therefore, in an effort to realize such an antenna, we created a slot aperture in the reflector of a typical Broadcasting Satellite (BS) antenna, and investigated its possible use as a UHF-band antenna element. Furthermore, a practical hybrid antenna for BS and terrestrial HD-TV was developed by implementing omnidirectional radiation in a parabolic reflector with a slot. This hybrid antenna exhibited excellent practical performance in a field test.
