Microstrip patch antenna is a low profile antenna which has low gain and narrow bandwidth. In this paper a RMPA at 2.4835 GHz is designed for mounting antenna in exposure system. Exposure system is a chamber made up of wood in which two antennas of same frequency mounted. One antenna is used for radiation while other one for reception. The RMPA designed using CST software with gain of 2.8647 dB. In exposure system animals like rats can be placed for observing effects from Wi-Fi systems. These effects are applicable to humans also. For observing effects gain is not sufficient so there is need of gain enhancement. There are numerous techniques of gain enhancement but I proposed antenna array technique. Antenna array which is a collection of radiating elements are very versatile and synthesize a required pattern that can not be achieved using single element. So here two rectangular patches of same size and frequency connected as an array. The gain of array system is 5.6692 dB. Hence there is 97.89% increase in the gain of RMPA.
