A panel array antenna (1) has a waveguide network (5) coupling an input feed (10) to a plurality of primary coupling cavities (15). Each of the primary coupling cavities is provided with four output ports (20), each of the output ports coupled to a horn radiator (25). The waveguide network is provided on a second side (50) of an input layer (35) and a first side (30) of a first intermediate layer (45). The primary coupling cavities are provided on a second side (50) of the first intermediate layer (45) and the output ports provided on a first side (30) of an output layer (75), 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 (50) of the output layer (75). Additional layers, such as a second intermediate layer (120) and/or slot layer, may also be applied, for example to further simplify the waveguide network and/or rotate the polarization. FIGURE 3
