A dual‐band monopole antenna for UHF‐band applications has been demonstrated in this work. The dual‐band characteristics are achieved using several strip monopole radiators. In addition, a small planar inverted‐F monopole antenna 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 (458–502 MHz) and 118 MHz (701–819 MHz). © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:896–900, 2014
