Design of high gain multiple U-slot microstrip patch antenna for wireless system

In this paper, a novel multi-slotted microstrip patch antenna with high gain is presented and discussed. The design adopts contemporary techniques such as probe feeding and multi-slotted patch. These techniques can contribute to the enhanced performance of the antenna. The design also employs a novel shape patch. By integrating these techniques the proposed design offers low profile, high gain and compact antenna element. The maximum gain at the resonant frequency of 2.45GHz is 11.35dBi. The lowest return loss can be -34.49 dB at 2.45GHz. The proposed design has a simple structure and a compact dimension of 87mm*51mm. The proposed design is suitable for particular wireless communication application such as WiFi and WLAN.
