In this paper, the authors present the design of a compact size, single feed, single layer, dual frequency Rectangular and Circular microstrip patch antenna for C Band applications. For the design and simulation they have used method of moment based EM Simulation software I3ED.With the introduction of slots at the edges of the rectangular and circular patch the size of the antenna has been reduced to 48% and 37%. They have also calculated Gain, antenna efficiency and radiation efficiency of the proposed antenna structures. The radiation patterns of the proposed compact rectangular and circular microstrip patch antenna are also studied.
