Abstract

A new design of ultra-wideband (UWB) micro strip patch antenna with notch band characteristic for wireless local area network (WLAN) application is presented in this paper. The proposed antenna consists of a rectangular patch with a partial ground plane that is fed by 50 Ω micro strip line. A notch band function is created by inserting overlapped one U-shape and one C-shape slot on the radiator patch, added additional patch to the ground plane side and slit in truncated ground plane. The proposed antenna potentially minimized frequency interference between WLAN and UWB system. This antenna with the size of 26 mm × 32 mm (W×L) and the simulated results show that the antenna can operate over the frequency band between 3.1 and 10.45 GHz for voltage standing wave ratio (VSWR) > 2 with band notch 5.06-5.825 GHz. Besides in the working band, the antenna shows good radiation pattern in the H-plane and the E-plane and has good time domain characteristic.

Highlights

Ultra-wideband technology has become most promising technology since FCC (Federal Communication commission) approved the 3.1-10.6 GHz band for unlicensed radio frequency applications
The UWB antenna with band notched characteristic is the best option to mitigate the interference between narrowband (WLAN) and UWB system
The proposed antenna composed of a rectangular patch is fed by a micro strip line and printed on FR4 substrate having dimension of 26 mm × 32 mm

Summary

Introduction

Ultra-wideband technology has become most promising technology since FCC (Federal Communication commission) approved the 3.1-10.6 GHz band for unlicensed radio frequency applications. It has the advantages of low power consumption, high data transmission, less complexity, low cost etc. The UWB antenna with band notched characteristic is the best option to mitigate the interference between narrowband (WLAN) and UWB system. Where it is clear that the proposed antenna has compact profile and desired notch band compare to others.
