An enhanced but simple single band Rectangular patch antenna is presented. This compact micro strip antenna is obtained by inserting small coaxial feed in a Rectangular patch antenna. The antenna has been designed and simulated on an RTduroid substrate with dielectric constant of 2.2 and thickness of 3.2mm.The design is analysed by finite element method based HFSS simulator software (version 13.0).The simulated return loss obtained is -31.4402db at 2.4GHZ respectively. Therfore this antenna is applicable for SHF band applications.
