Comparative Analysis of E–Shape and H-Shape Microstrip Slotted Antenna on the Basis of Return Loss and Bandwidth

icro-strip patch antenna is more popular as compared to other antennas and widely used today in modern wireless communication system because of its elegant weight, low fabrication price, easy to feed, ease to fabricate, easy to analyze, and attractive radiation characteristics. Though patch antenna has several advantages but has some disadvantages as well, like limited bandwidth and low gain. In last few years, Different techniques such as Electromagnetic Band Gap (EBG) structure, artificial magnetic conductor (AMC)/ and modifying the structure of microstrip patch antenna are used to overcome the above mentioned limitations. In this paper, we propose two different geometry shape antennas i.e. E and H-shaped which is developed from the rectangular patch and compare the performance of the proposed antennas on the basis of gain and Bandwidth with the same physical dimensions. The CST Micro studio simulator is used to study the antennas. Bandwidth and Return loss of E-shaped Antenna is much better than that of H-shaped antenna. The results obtained clearly demonstrations that, the implementation of the E-Shape is much better in term of bandwidth and return loss compared to the H-shaped patch antenna. So it’s better to use E-shaped antenna for modern wireless communication system.
