Abstract: Patch on the basis of modification of Rodman Lens Structure has been designed in this paper .A biconvex lens structure is prepared on perturbation of circular pattern of Rotman Lens Structure .This proposed antenna operation is on Ku band.For preparation of substrate, FR4 epoxy material is chosen with dimension of 80 mm × 80 mm and the ground plane and patch material is chosen to be copper .By log periodic implementation frequency is made independent of the nature of the antenna , so that the bandwidth can be enhanced . Both HFSS and CST software has been used for the simulation to calculate different parameters like S11, VSWR, antenna gain and directivity. To support the theoretical value, the fabrication is done accordingly, and the testing results found out to be in an agreement of the simulated results.
Keyword: Rotman Lens, FR4 Epoxy, Ku-Band, S-Parameter, VSWR, Antenna Gain.
Scope of the Article: Microstrip Antenna Design and Application.
