| Abstract(in English) | As a planar-type wideband antenna being useful for UWB radio systems, the authors have previously proposed a wideband dipole antenna being composed of leaf-shaped bowtie radiating elements. In this report, a leaf-shaped bowtie slot antenna, which is a complementary structure of the above-mentioned dipole antenna, is proposed and its characteristics are revealed by FDTD analysis and measurements. In the first place, the antenna having the operating frequency band from 7 to 10GHz (UWB high band) is designed, and its reflection coefficient is evaluated for the case when the feeding point is arranged in the center portion of the antenna. Based on the evaluated results, a feeding circuit for the proposed antenna is designed. Antenna characteristics for the case with the feeding circuit is evaluated with FDTD analysis and measurements in order to confirm the effective performance of the proposed configuration. In addition, it is revealed that unidirectional radiation characteristics can be achieved by placing the antenna over a reflector at an appropriate distance. |
