Analytical and experimental study of a planar antenna for improvement of deteriorated receiving characteristics due to fading phenomenon
ABSTRACT The fading phenomenon is one of the factors of quality deterioration in mobile communication technologies. A single-feed planar antenna which is composed of two antenna components, the planar monopole antenna (PMA) and the planar slot antenna (PSA), is proposed for improvement of deteriorated receiving characteristics due to fading phenomenon. Antenna characteristics of proposed antenna and its components which are analyzed by the FDTD (Finite Difference Time Domain) method are obtained. Return loss characteristics and radiation patterns are compared analytically and experimentally. It is found that analyzed results correspond well with experimented results, and the proposed antenna has a resonant frequency with a function of the PMA and the PSA from current distribution. Moreover, it becomes evident from the results of field experiment that the proposed antenna can improve the receiving characteristic.

ABSTRACT: 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).Antennas and Propagation (APSURSI), 2011 IEEE International Symposium on; 08/2011
