Abstract 

This work introduces an E-plane hollow waveguide antenna array feeding network to feed 4 units of 2x2 sub-arrays as aperture elements. The feeding network and the sub-arrays are built as one object and fabricated using 3D-printing technology. The material used in 3D-printing is polymer and the cavity of the antenna array with the feeding network were metalized using sufficient layer of conductive silver epoxy. The introduced design exhibits an 18% bandwidth at center frequency of 14 GHz with a gain of 16 dBi.
