Proposed Design for Circular Antenna and Half Ring Antenna for UWB Application
In this paper, Ultra wideband planar circular patch and half circular ring patch antennas are proposed. These newly simulated structures are proposed for fabrication. The antennas are suitable for operating frequency of 7.5 GHz. It is shown that return loss of the both the antennas at 7.5 GHz is better than -10 dB. The VSWR obtained is less than 2. The half ring patch antenna is found to have the compact size and more bandwidth as that of circular patch antenna. HFSS11 is used for the simulation. From HFSS11 simulations, dimensions of antennas are chosen for better performance. Details of the proposed antenna design and measured results are presented in this paper.
