Abstract

An asymmetric coplanar waveguide (ACPW)-fed zeroth-order resonant (ZOR) antenna with extended bandwidth is investigated. By embedding a strip connected between the metallic patch and an ACPW ground plane, another resonant frequency at 2.53 GHz is achieved. The bandwidth enhancement of designed antenna can be obtained when the zeroth-order resonant frequency and the resonant frequency at 2.53 GHz are merging together. The size of the antenna is only 15×22×0.8 mm3 with simple planar structure. A prototype of the proposed antenna has been constructed and experimentally studied. The measured results show that operating bandwidths with 10 dB return loss are about 510 MHz (2.49-3.0 GHz), the simulated peak gain of 1.59 dBi at 2.68 GHz, which is suitable for WiMAX (2.5 GHz-2.69 GHz) application.
