Abstract:

The multiband U slotted patch antennas are usually designed with complex feeding such as L- probe, M- probe feedings. In this paper, a multiband microstrip patch antenna with simple strip line feeding, which enables a handheld communicating device to support different wireless applications, is proposed. The antenna can efficiently support for different bands with their centre frequencies as 1.9GHz, 2.4GHz, 3. 3 GHz coming under the bands of different wireless applications as GSM, Bluetooth, WLAN/WIFI, WiMAX and some defence applications such as radio navigation. To obtain the multiple bands, multiple U- slots are provided with the rectangular patch and to provide impedance matching, the feeding position is varied along the edge of the patch, thus availing efficient radiation. The proposed design has the advantage of having simple feed and the structure remains single layer and single patch. The simulated results (using Ansoft HFSS) of the proposed antenna are presented and a good agreement is observed between them.
