H‐plane corporate waveguide‐fed 4‐aperture‐stacked circular microstrip patch linear array for Ku band applications

In this article, a linearly polarized 4‐element linear array in Ku band is presented. The single element consists of a circular microstrip patch capacitively coupled to a printed slot‐end WR‐51 waveguide. A corporate waveguide feeding network at H‐plane is designed, which is composed of bends, T and...

Description
Summary:In this article, a linearly polarized 4‐element linear array in Ku band is presented. The single element consists of a circular microstrip patch capacitively coupled to a printed slot‐end WR‐51 waveguide. A corporate waveguide feeding network at H‐plane is designed, which is composed of bends, T and Y‐junctions. An optimization process with septums and irises is performed to get the best possible matching coefficient. An antenna prototype has been manufactured and measured. A maximum gain of 12.6 dBi, up to 91.6% radiation efficiency and 13% bandwidth (16 to 18.3 GHz) has been experimentally achieved.
