Abstract—Micro strip patch antenna became very popular today because of its ease of design, fabrication, low cost, light weight, easy to feed and their superior radiation characteristics. Although patch antenna has numerous advantages, it has also some drawbacks such as restricted bandwidth and low gain. Many antenna engineers have developed various techniques to improve these parameters, however the performance of these antennas need to be further improved. This paper is focused on the improvement of gain of the rectangular slotted patch antenna at 2.0675 GHz by inclusion of notches into the design and to compare their results. The antenna is fed by Inset feeding technique, which is simple and obtaining good impedance matching. The antenna design has been simulated using the CST studio suite tool. Comparative study of simulated parameters like Gain, Bandwidth, Directivity and Radiation pattern have been done and presented in this paper.
