Abstract

The microstrip patch antenna (MPA) are widely used as the advantages were low profile,easy to fabricate and also low cost.The performances characteristics of a single MPA can be improved and enhanced by using microstrip patch antenna array.There are several ways to improve the performances of the microstrip patch antenna such as slotting technique,defected ground structure or by making it as an array.In this project,array have been chosen to enhance the performances of MPA.Therefore,this project was conducted to give a comparative analysis of between a single MPA and 2 x 1 rectangular MPA array for Wi-Fi application.Both of the antenna were designed and simulated at 2.45GHz operating frequency.The substrate used was FR-4 dielectric and simulations are performed by using CST Software.The antennas then was fabricated to validate the performances of antenna by doing measurement. The feeding techniques of rectangular MPA was inset feed as for matching the impedance load with the antenna in order to maximize the power transfer or minimize the signal reflection from the load.The results of simulation and measurement show that there were enhancement of the parameters of the antenna.The bandwidth for antenna array from simulation and measurement were 0.07894GHz and 0.11GHz respectively. Other than that, the gain of simulation was 5.42dB and 6.425dB of gain from the measurement for antenna array. Based on the results,the antenna can be applied in Wi-Fi application which is frequency range between 2.3GHz to 2.5GHz.
