The characteristics of the batwing radiator, which is the heart of the superturnstile antenna system for VHF-TV broadcasting, are broad bandwidth. We investigate the modified batwing antenna for UHF used for digital terrestrial broadcasting. The characteristics of the 2-element modified batwing antenna with an infinite reflector and with a wire screen for the finite reflector are calculated by NEC-Win Pro. These antennas are connected with each element by a parallel feed line and fed at the center of this line. We estimate these antennas from 470 MHz to 770 MHz of the UHF-TV broadcasting band in Japan. The broad-band properties and the power gain of about 11 dBi are obtained in these frequencies.
