Abstract

In this paper, a single-feed planar antenna for electric and magnetic fields reception (SPAEM) is proposed in order to decrease the change of received signal level and improve the receiving signal quality. The SPAEM is composed of a line element and a conducting ground plane with a slot which are printed on the dielectric substrate. The antenna has two functions. One is the function of a planar monopole antenna (PMA), and the other is the function of a planar slot antenna (PSA). Therefore, this antenna can receive both electric and magnetic fields by a single feed point. Return loss characteristics, current distribution, and radiation patterns are analyzed by the FDTD method. It is shown that the characteristics of the SPAEM combine those of the PMA with those of the PSA. The antenna keeps an independent resonant frequency even if the PMA and the PSA were combined using single feed structure. These results are described.
