Analytical study of broadbanding of a planar antenna for improving the deteriorated characteristics due to fading phenomenon

The fading phenomenon due to standing waves is one of the factors of quality deterioration in mobile communication technologies. A single-feed planar antenna which is suitable for receiving the terrestrial broadcasting in UHF (Ultra High Frequency) band is proposed in order to improve the deteriorated receiving characteristics due to the fading phenomenon. It has two antenna components; a B-PMA (Broadband Planar Monopole Antenna) which is an electric antenna and a B-PSA (Broadband Planar Slot Antenna) which is a magnetic antenna, and is composed of the two components by single-feed structure. The return loss characteristics of the proposed antenna and its components are analyzed by the FDTD (Finite Difference Time Domain) method, and declare that the bandwidth of the proposed antenna is broadened to receive the Japanese terrestrial DTV (Digital Television).
