Dual band bent slot loaded patch antenna

By Author

A planar UWB antenna with added GSM 1800/WMTS and UMTS bands is presented. A CPW-fed circular patch is used to obtain wideband characteristic covering the UWB range. A novel slot formed by merging the alternate sides of a hexagon with isosceles triangles is inserted in the patch to obtain dual-band operation with the lower band suitable for GSM 1800 operation.

By using this technique the resonant frequency can be lowered, and hence reduce the size of the AMC.

A NOVEL DUAL-BAND PATCH ANTENNA FOR WLAN … low costs. Dual-band operation is an important subject in microstrip antenna designs [5,6]. Recently, several designs of the dual-band slot-loaded microstrip antennas have been reported [7{9]. These related dual-band designs are achieved by embedding a narrow arc-shaped slot or placing an open-ring slot close to the boundary of the patch [10,11].

The proposed antenna is a dual band microstrip patch antenna using U-slot geometry. The operating frequencies of the proposed antenna are chosen as 2.4 and 0.9 (GHz), obtained by optimizing the physical dimensions of the U-slot.
