Gain improvement & return loss reduction of microstrip patch antenna at 6.45 GHz using multi slotted patch for mobile applications in comparison with coaxial probe feed.

The main objective of this project is to design a rectangular-shaped microstrip patch antenna with microstrip line feed at a frequency of 6.45GHz to improve the Gain and Return Loss of Antenna by using Multi Slotted Patch for Mobile Applications. Microstrip patch antenna with Multi Slotted Patch using microstrip line feed and Multi slotted patch Antenna with Coaxial probe feed technique is used with a sample size of 20 by keeping alpha error is 0.05, Threshold by 0.05, 95% confidence interval, pre-test power 80%. By using HFSS Simulation Software Gain and Return Loss of Microstrip patch antenna appears to be improved and noted in comparison with Coaxial probe feed antenna with the multi slotted patch. The Simulation Results obtained for the designed antenna are Gain is 6.662dB and Return loss is -18.33dB. Attained significance accuracy ratio p(<0.05) for Gain and return loss in SPSS Statistical Analysis. Performance parameters of Microstrip Patch Antenna with Multi Slotted Patch using microstrip line feed appears to be improved when compared with Multi slotted patch antenna with coaxial probe feed. From the results, the proposed antenna can be used for Mobile Applications. [ABSTRACT FROM AUTHOR]
