Abstract:
In this paper the circular patch structure is modified in accordance to the Rotman Lens to operate in the X-band whose frequency range is defined by the IEEE as 8 GHz to 12 GHz. The antenna is designed on a FR4 epoxy substrate having a relative permittivity of 4.4 and then patch structure is found out using MATLAB program. To operate all over the frequency range of X-band the log periodic implementation of the antenna is done by the frequency scaling method .All the simulation work is carried out by the CST software. The return loss, VSWR, directivity and gain of the proposed antenna are analyzed from the simulation results.
