Abstract: In this paper, a rectangular patch antenna with slits for dual band capabilities is presented. The suggested antenna works for two frequencies which are at 2.5 GHz and 5.1 GHz. The first operating frequency is in the band of 2.3 to 2.7GHz with -16.8dB reflection coefficient at 2.5GHz resonating frequency, whereas the second band is 4.6 to 5.5GHz with -29.2dB reflection coefficient at 5.1GHz resonating frequency. The simulation results exhibit that, the suggested antenna works for dual band frequency having impedance bandwidth of 482 and 844 MHz respectively. The gain is observed as 2.9 dBi and 4.2 dBi of respective bands. The first frequency band can be used for Industrial, Scientific and Medical(ISM) applications and second frequency band can be used for C-band applications.
