Efficient and optimized design of a stacked patch microstrip antenna for next generation network applications

摘要

WiMAX technology is an emerging technology for next generation network. It is a wireless broadband communications technology based around the IEE 802.16 standard providing high speed data over a wide area. Although initially seen as a candidate for 4G, its use is decreasing, although it is used as WiMAX broadband and also for last mile links. In this paper, An Aperture coupled Stacked Patch Microstrip Antenna for WiMAX application is proposed. This antenna is designed to have H-shape patch with V shape slot at the ground to provide the WiMAX band (3.3-3.6 GHz) which is a licensed spectrum that has been allocated for broadband wireless access in numerous countries around the world and widely used in military applications. FR4 is used as the substrate material. The designed antenna is simulated using Ansoft High Frequency Simulation Software. The simulated and measured results are showing that the proposed antenna is producing the bandwidth of 300 MHz with the return loss value of - 25.1 dB.
