Abstract

Microstrip patch antennas (MPA) are used for communication applications due to their small size and low cost. Lower gain and narrow bandwidth are the major drawbacks of a patch antenna. Therefore, slotting and defect ground structure (DGS) is used in order to make the antenna able to achieve higher gain and larger bandwidth. Furthermore, the antenna are able to operate at multiband of frequency which are 2.4 GHz, 4.1 GHz and 4.8 GHz. Microstrip patch antenna is simulated in CST software and followed with fabrication process. Result are compared between conventional antenna with simulation and measurement result of multiband microstrip patch antenna. Result show that enhancement of bandwidth is achieved if compared to the conventional antenna. The bandwidth for simulation conventional antenna is the bandwidth for frequency 2.4 GHz is 76 MHz from 2.45 GHz to 2.53 GHz, for frequency 4.1 GHz is 183.2 MHz from 3.97 GHz to 4.15 GHz. and for frequency 4.8 GHz is 246 MHz from 4.75 GHz to 5.0 GHz. The bandwidth for simulation multiband microstrip patch antenna is the bandwidth for frequency 2.4 GHz is increased to 100.9 MHz from 2.38 GHz to 2.49 GHz. Furthermore, the frequency 4.1 GHz is 182.7 MHz from 4 GHz to 4.18 GHz and the bandwidth for frequency 4.8 GHz is increased to 405.4 MHz from 4.60 GHz to 5.01 GHz. The return loss magnitude achieved below than -10 dB with application of slot and defect ground structure on the antenna. As a result, the antenna can operate in WiMAX frequency range (2.5 GHz to 5.8 GHz) and therefore suitable for WiMAX application.
