Description	275-281 The radiation performance of a circular patch microstrip antenna having a concentric diamond shape slot has been presented in this paper. The side lengths and angles of the inserted diamond shape slot have been optimized to achieve a single layer multi frequency microstrip antenna applicable for C band space communication systems. For simulation work, IE3D simulation software has been applied and later this antenna has been designed and tested by applying glass epoxy FR-4 substrate. The proposed antenna provides much improved bandwidth (measured impedance bandwidth 0.87 GHz or 13.58%) than a conventional circular patch antenna. The gain of proposed antenna is almost constant in the frequency range where broadband performance is realized, however, it is improved considerably in comparison to a conventional circular patch antenna. The performance of proposed antenna has been compared with that of a conventional circular patch antenna having identical patch radius. The measured co and cross polar patterns of proposed antenna at one of the three resonance frequencies have been presented.
