A Dual-Band Single-Feed Switched Beam Antenna for WLAN

Abstract

Abstract-This article presents the dual-band of a single patch antenna that can operate at a frequency of 2.47 to 5.04 GHz, which is available in WLANs (IEEE 802.11). The beam pattern of the antenna can be switched by changing the position of shortedcircuit points at each edge of the antenna. The advantage of the proposed antenna is that it is a simple structure which is small in size, weighs little and has an easily adjustable beam. In addition, the antenna is tested under real circumstances using the existing WLAN infrastructure. The results confirm that the signal strength can be improved when the proposed switched beam antenna is utilized.

A single element of multiband switched beam antenna for 5G applications

“…Also, an octagonal patch which fixed feeding point at the center, radiation patterns can be controlled by shorted circuited condition at end edges were revealed in [29], [30]. Moreover, the work proposed in [31], a compact dual band switched beam antenna which radiation patterns can be steered by controlling shorting positions at end edges. Next, a single element switched beam antenna using parasitic element to point main beam directions were presented in [32], [33].…”
