Abstract

A compact wideband antenna consisting of a L-shaped radiating element which has a modified inverted-F structure and a C-shaped parasitic radiating element on the ground is proposed. Three resonant frequencies and a very wide operating band are obtained. A prototype of the proposed antenna has been constructed and experimentally studied. The measured results show that the operating bandwidth with 10 dB return loss is about 2.9 GHz (2.11-5.01 GHz), 81.46%, respectively, covering LTE2500 (2.5-2.69 GHz), 2.4 GHz WLAN and 2.5/3.5 GHz WiMAX bands. Furthermore, the antenna has a simple planar structure and small volume of only 30 × 30 × 1.6 mm³. Good radiation characteristics and acceptable peak gains are obtained over the operating bands.
