Abstract
In this study, a design of high gain reflector antenna for point to point communications is reported. A probe-fed waveguide aperture with four-stacked-coupling aperture is employed to be a primary illuminated parabolic reflector antenna. By varying distance between the primary and secondary antennas, its gain can be raised. An EM simulator has been used in the process. It is found that this proposed antenna provides an excellent symmetrical sharp beam with a low side lobe level as well as low cross-polarization. In addition, this proposed antenna produces a high gain of 26.9 dBi with S11 < -15 dB from 0.88fc to 1.06fc. All simulation results are reported and discussed in the paper.
