Abstract-This paper presents the utilization of slots with full and partial ground plane in rectangular Microstrip Patch Antenna (MPA). The partial ground plane has been introduced to increase the bandwidth of designed antenna. Proposed antenna is designed on FR4 glass epoxy substrate with 1.6mm thickness and dielectric constant 4.4. Designing and simulation has been carried out by using HFSS V13 software. MPA with full ground plane works on four resonant frequency bands, but the value of gain and bandwidth is less. Proposed antenna with varying partial ground plane has been designed and observed that it adorns the optimal results at ground length 12mm. The MPA with partial ground plane with ground length 12mm works on two resonant frequency bands (2.21GHz and 7.06GHz) with the value of gain (3.92dB and 4.71dB) and bandwidth (949MHz and 1030MHz) respectively. These values are at the acceptable level which meets the requirement of wireless application such as bluetooth (2.41 -2.49GHz) and point to point high speed wireless communication (5.92 -8.5GHz).
