ResumenIn 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.
