Abstract

Recent advancement in WiMAX and similar applications need the antennas of broad bandwidth, small size, high gain, and enhanced efficiency. Microstrip patch antennas are widely used in these applications due to advantageous features like compactness, light weight and high efficiency. However, one of the major limitations of the microstrip patch is the narrow bandwidth. The objective of this project is to design, construct and fabricate a rectangular U-slot antenna for WiMAX applications to operates at frequency range of 2.8-4.8GHz, to achieve a dual band of WiMAX frequency. This antenna is fed by a microstrip feeding line. The antenna was fabricated on FR4 substrate, that has a relative dielectric constant, .sr = 4.3, a loss tangent tan 6 = 0.001 and thickness, h of 1.6 mm. Transmission feed Iine is used due its better impedance matching capabilities than the inset feed technique. The characterestic of each parameter of the antenna was analysed by using CST simulation. This analysis is important to determine the effect of the each antenna parameter to the output of the antenna. Insertion loss and return loss are two important responses to be observed. The fabricated antenna is tested using network analyzer.
