Wideband Antenna Array For C Band Applications
Abstract
A Wideband antenna array is proposed for the C-band applications. Proposed antenna is a eight element corporate feed antenna with a coax feed. The radiating element is a diagonally truncated rectangular patch with two symmetric slots on either side of the patch. The symmetric slots are used to get the necessary bandwidth and the diagonal truncations are used to get right hand circular polarization. The simulation results show that the proposed antenna is radiating at 5.72 GHz with a return loss of –20.62 dB and a band width of 132 MHz ranging from 5.630 GHz to 5.762 GHz. The gain of the antenna is 14.81 dB with a beam width of 400 and a side lobe level of 13 dB. From the obtained simulation results it is evident that the proposed antenna is best suited for the C-band applications.
