Low-Profile VHF/UHF Antenna for Vehicle

Many projecting rod-type antennas, which stick to vehicles, are spoiling vehicle proportion and making wind shield noise. A flat and low-profile antenna, especially which can be conform to the vehicle body's contours.

This paper proposes a new flat and low-profile antenna. The developed Band-Combining Flat (BCF) antenna is composed of multiple antenna elements, each characterized by high gain but narrow bandwidth. In order to realize TV reception, we have developed a band combining technology for the plural antenna elements.

The characteristics of the BCF antenna are verified on a surface of an actual vehicle. The BCF antenna has performance for fine reception of TV broadcasting in VHF and UHF bands with high gain characteristic.
