Determination of Dielectric Properties of Bismuth Titanate (BiT) Ceramic Material for WiMAX/WLAN Antenna

Abstract

The utilization of Bismuth Titanate (BiT) as a ceramic material on an antenna has been investigated. The BiT ceramic material is of interest for a range of Wireless Local Area Network (WLAN) IEEE 802.11 b/g and Worldwide Interoperability for Microwave Access (WiMAX) IEEE 802.16 application, which covers the range of 2.3 GHz to 2.5 GHz. The BiT ceramic material had been tested to own a high dielectric constant of εr= 15 that is able to miniaturize an antenna. There is a high demand nowadays on the miniature antenna for smaller devices. An experimental prototype at WiMAX/WLAN range was built and measured on its dielectric properties, especially the dielectric constant and dielectric loss of the prototype material.
