Switchable beam antenna

Abstract

This paper introduces the Switchable Beam antenna which has the ability to shift the direction of the Wi-Fi signal to any specific direction depending on the availability of user. The designs of eight radiating patches are installed in between aluminum plates which are fixed by the edges of the other aluminum plate. This is to represent eight angles where the antenna will radiate. By using switches, the beam of the radiating energy can be adjusted to be directed to a specific area. This antenna is operational at 5.8 GHz which is Wi-Fi frequency. The antenna generated a gain of 4.07 dB while the directivity is 9.986 dBi. Apart from Wi-Fi applications, the design can be customized in different frequency to support different application such as GSM.
