In today’s modern communication industry, antennas are the most important components required to create a communication link. Microstrip antennas are the most suited for aerospace and mobile applications because of their low profile, light weight and low power handling capacity. They can be designed in a variety of shapes in order to obtain enhanced gain and bandwidth, dual band and circular polarization to even ultra wideband operation. This paper provides a detailed study of the design of probe-fed Rectangular Microstrip Patch Antenna to facilitate effects of changing the feed point. By this paper we conclude that in the same patch we can take different feed points and same patch can be used for various applications. The main aim of this paper is to design various MSA for and analyze there results. For this first we simulate the results in IE3D and then we test these results practically after designing the hardware of the patch. In testing we find that our designed Microstrip antenna is very useful in Bluetooth technology for communication. The design parameters of the antenna have been calculated using the transmission line model and the cavity model. For the simulation process IE3D electromagnetic software which is based on method of moment (MOM) has been used.
