Antennas is the essential part of the wireless communications. Most of them are Microstrip Patch Antennas, Monopole antenna, and Folded Dipole Antennas. Each antenna is good in their own properties and usage. It can be said that antennas are the backbone and almost everything in the wireless communication without which the one cannot imagine wireless communication. This paper presents the designs of Rectangular microstrip patch antenna for 5.8 GHz communication. One of the antennas is Rectangular Microstrip Patch Antenna (RMPA) and Second Rectangular Microstrip Patch Antenna with defect ground structure. Basic property of both the antenna like simulated design, Return loss, directivity, Radiation Pattern and bandwidth are discussed. This work shows that bandwidth of Antenna in RMPA with DGS is increased about 39.57% which is great deal in antenna designing system, return losses of designed antenna is also decreased by 25.923%, gain and directivity of the proposed antenna is almost same. Rectangular Microstrip Patch Antenna with DGS also reduces the size of antenna which is always a basic need of Patch antenna design system.
