A dual-band multiple-strip monopole antenna

A new design of the dual-band monopole antenna with the strip-line topology has been shown in this study. The dual-band characteristics are achieved using several strip monopole radiators. A small planar inverted-F monopole antenna (PIFMA) is connected to the ground plane. The bandwidth improvement for the antenna is obtained mainly by modifying the geometrical configuration of the strip monopoles added at the antenna and the ground plane. The measured results of the impedance-bandwidth are about 44 MHz (458 to 502 MHz) and 118 MHz (701 to 819 MHz).
