- Abstract
A feeding antenna that uses a rectangular waveguide with a patch on it to equalise the principle planes is proposed. The patch is printed on a substrate grounded with shorting pins. Typically, corrugated horn antennas are used for feeding antennas, but they are expensive because of the complex fabrication process. In comparison, the proposed antenna is inexpensive because it uses a rectangular waveguide and a dielectric substrate. The simulation and experimental results gave similar 10 dB beamwidths, while the beamwidth of the conventional waveguide was markedly different. The proposed antenna could be used as a feeding antenna for reflectors at low cost.
