Antenna is a transducer which plays a significant role in wireless modern communication. The major drawback of microstrip antennas is low gain which is a product of directivity and efficiency. The objective of this work is to design a novel microstrip slotted patch antenna NMSPA with enhanced directivity at operating frequency of 5GHz. It has been simulated over teflon material using Altair Feko software. NMSPA is designed to improve the directivity and gain when compared with Rectangular Microstrip Patch antenna(RMPA). Their results were analysed by SPSS software with the help of 40 samples whose significance value is less than 0.05 and pretest power of 80%. From the feko simulation result, NMSPA has a peak gain of 8.58dB and directivity of 8.81dB. RMPA has a peak gain of 6.31dB and directivity of 6.31dB. Proposed antenna appears to have better gain and directivity as compared to RMPA.
