Abstract

A simple wideband antenna with parasitic element is proposed in this paper. The printed antenna is comprised of an L-shape monopole and a parasitic element. By optimizing geometrical parameters of the parasitic element structure, a good impedance bandwidth which covers DVB (470 MHz~702 MHz) for return loss being higher than 5 dB and LTE/700(704 MHz~787 MHz), GSM850/900 (824 MHz~894 MHz/880 MHz~960 MHz) for return loss being higher than 10 dB is achieved. A fabricated antenna has a dimension of 150 mm×56 mm. The measured and simulated efficiency, gain and radiation pattern which is quasi omni-directional in the yoz plane make it to be a good candidate of mobile communicational terminals.
