A ku Band Circular Polarized Compact Antenna For Satellite Communications

Abstract

A minimal rectangular patch antenna intended for the satellite correspondences with a working recurrence of 13.04GHz is presented. Radiator is shortened at the slanting edges and two openings are scratched in the patch in L shape alongside a round ring space at the focal point of the radiator to get the circular polarization. Rogers RT Duroid 5880 is substrate and a 50ω coaxial link is utilized to energize antenna. The general component is of size 13mm×13mm×0.508mm which is 0.56λ×0.56λ making it a smaller one. A impedance data transfer capacity of 25MHz going from 12.92GHz to 13.16GHz with an gain of 7.44dB at the working recurrence of 13.04GHz. The axial ratio of the antenna at the working recurrence is 2.78dB. Economically accessible 3D test system software programming has been utilized to plan the antenna.
