Abstract

A new coplanar waveguide (CPW)-loop combination feed wideband directional and compact multilayer microstrip antenna is presented for UWB applications. The antenna consists of two dielectric layers; CPW-loop on the ground plane, main patch on the middle layer and four asymmetric parasitic patches on the upper layer. The feed consists of a CPW structure and a loop on a ground plane. The antenna has a measured 10dB return loss bandwidth of 36% (3.12GHz to 4.51GHz) and maximum gain more than 5dBi over the 48% (3.0GHz to 4.90GHz). The total thickness of antennas is 4.65 mm. The proposed technique is very useful for designing wide bandwidth antennas on multilayer printed circuit board.
