Microstrip Antenna Array for WiMAX & WLAN Applications

This paper presents the design of microstrip rectangular patch antenna with center frequency at 2.4 GHz for WiMAX & WLAN application. The array of four by one (4x1) patch array with microstrip line feeding technique was designed and simulated using Computer Simulation Tool (CST) Microwave Environment software. The antenna array designed on Roger5880 substrate with overall size of 200 x 100 x 1.59 mm3 and dielectric substrate with �� �� = 2.2. This antenna structure is designed by using CST Software based on the characteristic impedance for the transmission line model. The performances of designed antenna are compared in terms of parameters like substrate dimension, feed size and ground plane. The antenna performance in terms of its frequency domain and time domain characteristics are investigated.
