摘要:A sensitive antenna attached to the rear window of a car has been designed for diversity reception of digital terrestrial television broadcasting. The proposed antenna efficiently utilizes heat wires located on the rear window and the antenna elements to improve the directive gain in the horizontal direction. The field tests show that the proposed antenna using heat wires gives an antenna gain of 2.5 dB compared to the conventional rear-window half-wavelength dipole antenna. By computer simulation, we also show that the proposed diversity scheme, which is composed of two wire antennas with heat wires, can improve the gain in the front direction.
