A device includes a modem having a first feed port and a second feed port. A first planar dual-polarized sub-array has a first beamwidth and includes a first orthogonally polarized element communicatively coupled to the first feed port and a second orthogonally polarized element communicatively coupled to the second feed port. A second planar dual-polarized sub-array has a second beamwidth and includes a third orthogonally polarized element communicatively coupled to the second feed port and a fourth orthogonally polarized element communicatively coupled to the first feed port. The first dual-polarized sub-array and the second planar dual-polarized sub-array generate a collective beamwidth that exceeds the first beamwidth and the second beamwidth.
