Simple Printed Antenna With Parasitic Element for DVB-H, Lte/700 and GSM Handheld Terminals

Abstract

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. The protype of the antenna is in size 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.
