The deterioration of received signal level, namely fading phenomenon, is enumerated in a factor of quality degradation in mobile communication technologies. The improvement of fading phenomenon is desired in the mobile communications for a long time. Authors have proposed a single-feed planar antenna which is composed of a planar monopole antenna(PMA) and a planar slot antenna(PSA), and analyzed the...
The broadband planar antenna with an elliptical element and a ground conductor with a slit is proposed. The position of a feeding point of proposed antenna is offset from center of ground conductor. The proposed antenna is analyzed by using FDTD method, and is discussed for return loss characteristics and radiation patterns. It is cleared that offsetting the feeding point is effective for broadbanding,...
Recently, ultra wideband (UWB) system has become one of the most useful technologies in the room communications. In this paper, characteristics of return loss of a basic E-type planar antenna (BEPA) and a half-BEPA (H-BEPA) are considered for the length of elements. In order to make the broadband characteristic in a H-BEPA, a H-BEPA with an elliptical element is proposed and analyzed by the FDTD method...
In this paper, we propose a planar antenna which has an elliptical element and a ground conductor plane which are printed on a dielectric substrate. The position of the feeding point of the antenna is offset from the center of the ground conductor plane with a slit. The characteristics such as return loss and radiation patterns of the proposed antenna are analyzed by using the FDTD method. From these...
