Abstract
A panel array antenna has a waveguide network coupling an input feed to a plurality of primary coupling cavities. Each of the primary coupling cavities is provided with four output ports, each of the output ports coupled to a horn radiator. The waveguide network is provided on a second side of an input layer and a first side of a first intermediate layer. The primary coupling cavities are provided on a second side of the first intermediate layer and the output ports provided on a first side of an output layer, each of the output ports in communication with one of the horn radiators. The horn radiators are provided as an array of horn radiators on a second side of the output layer. Additional layers, such as a second intermediate layer and/or slot layer, may also be applied, for example to further simplify the waveguide network and/or rotate the polarization.
