| Abstract: | 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. |
