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.
Conference Proceeding: Characteristics of single-feed planar antenna for improvement of fading phenomenon[show abstract] [hide abstract]
ABSTRACT: The characteristics of proposed antenna such as return loss and radiation patterns from both sides of measurement and calculation were obtained. From these results, it is understood that proposed antenna has both functions of the PMA and the PSA with single-feed structure. Therefore, it seems that proposed antenna is an effective planar antenna in order to improve the receiving signal quality. In future, an experimental system to confirm and verify the improvement of the deterioration of receiving signal quality will be considered.Antennas and Propagation Society International Symposium, 2009.
