Abstract

Abstract: A design and simulation of the mode converter antenna (MCA) with right‐hand circular polarization, at 10 GHz frequency, is presented. The circularly polarized mode converter antenna (CPMCA) consists of two inner conductors and a body. The TEM mode is converted into a circular polarization TE11 mode, using the inner conductors connecting the coaxial waveguide in two vertical and horizontal directions. The sidelobe level is less than −15 dB at the working frequency. The S11 and axial ratios of the CPMCA are about −16.5 and 0.15 dB, respectively. Also, the axial ratio is in the acceptable range.
