| ABSTRACT |
The antennas are designed and constructed with a combination of six-BiT Dielectric material in an array form stacked on a RO 5880 microwave substrate. The impedance bandwidth of the dielectric material antenna is 350 MHz, and it is able to operate in the frequency range of 2.20 to 2.55 GHz, which is suitable for the application of WiMAX and WLAN, 2.30 GHz and 2.40 GHz system respectively. The utilization of a bismuth titanate (BiT) dielectric material that covers about 90% of the antenna led to high radiation efficiency, low cost, and the production of small-size antennas. High-dielectric constant rectangular bismuth titanate antenna for WiMAX and WLAN application has been investigated, fabricated, and measured to ensure the performance of the antenna is better than the conventional antenna.
