“Design and Analysis of Microstrip Patch Antenna with Air-Gap for Narrow Bandwidth Applications”

This work investigates microstrip patch antenna design with an integrated air gap for performance enhancement through optimization. The antenna has been designed using an air gap and employing a U-shaped slot and Rogers R04003C substrate. We aim to enhance crucial antenna parameters such as gain and bandwidth. Through extensive simulations and analysis, we have achieved a gain of 8.66dBi and a bandwidth of 4.5 GHz. The S11 obtained is -20 with a gain of 8dBi. These findings provide valuable insights for further examination and verification. The proposed antenna design exhibits promising potential for narrow-band applications such as Shortwave communication systems, RADAR Technologies, and Medical Applications. This research contributes to the advancement of antenna technology and its practical implementation
