Compact Dual Band Patch Antenna with EBG Structure with U Shaped Slot for Dual Band Operation

Subhrajyoti Majhi | Naresh Chandra Naik


Abstract: A patch antenna which is performed in dual band operation with u shaped slot cut in the front part and the EBG structure with square EBG structure in the back side of the antenna is reviewed in the paper. The analysis is based on by doing careful consideration of the microstrip patch antenna in different iterations. In iteration 1 first the simple microstrip patch antenna with electronics band gap structure at back portion of antenna is simulated. In the iteration 1 the antenna is operated in single band frequency at 2.472 GHz and the reflection coefficient of the antenna is operated at the -29.472. To enhance the frequency and the antenna that to be operated in the dual band and the antenna size to reduce we have done the operation in phase wise iteration. In the iteration first the microstrip patch antenna is simulated with EBG structure at the back side of the antenna and after careful consideration of the different iteration the final antenna that to be evaluated is of patch antenna with EBG structure at the back side of the antenna and in the front side dual u shaped slots are to be cut in the front position of the antenna is need to be proposed and the antenna is need to be operated at the dual band and the frequency of the antenna to be operated at the 2.448 GHz at reflection coefficient at -17.54 and another frequency of operation at 4.7732 GHz and the reflection coefficient of the antenna is at the -14.17. The final antenna that is proposed is the microstrip patch antenna the substrate of the antenna is of FR4 and the patch of the antenna is built of copper material. The final antenna with dual u shaped slot and the EBG structure at the back side of the antenna the gain of the antenna is 2.168 db and the directivity of the antenna is at 5.221 db. The antenna is shows the 2.168 db gain and directivity 5.221 GHz at the 2.448 Ghz and at 4.7732 GHz frequency the antenna shows the 5.009 db directivity and the 2.098 db gain. The proposed antenna is suitable for working in dual band operation at 2.4 Ghz frequency and another at 4.7732 GHz frequency and working at a high gain of the 2.168 db and directivity at the 5.221 db. The antenna performance and the simulation results are analysed by using the CST STUDIO SUITE Software. The antenna is free for working with wide range of frequency and free to work in like ISM band operation(2.4-2.5 GHz) band.
