Abstract: A compact Circular polarized rectangular patch antenna has been designed for the Deep Space applications in the Ku band with an operating frequency of 13.15GHz. The patch has been truncated at the diagonal corners and two L shaped slots are been etched in the patch to get the circular polarization. A 50Ω coaxial cable has been used to excite the antenna. The overall dimension of the antenna is 13mm×13mm×0.508mm which is 0.65λ×0.65λ making the proposed antenna a compact one. The Proposed antenna is having an impedance bandwidth of 25GHz ranging from 13GHz to 13.25GHz with a gain of 7.82dB at the operating frequency of 13.15GHz. The axial ratio of the antenna at the operating frequency is 2.94dB which indicate the circular polarization. Low cost FR4 material is been used as the laminate base for the antenna which will act as the dielectric material.
