The present disclosure is directed to a dual-polarized antenna array including a first BAVA, a second BAVA and a cradle assembly. The cradle assembly includes first, second and third U-channel modules connected via first and second frame portions. The first U-channel module, the second U-channel module, and the first frame portion receive first, second and third edge portions of a substrate of the first BAVA, respectively. The second U-channel module, the third U-channel module, and the second frame portion receive first, second and third edge portions of a substrate of the second BAVA, respectively. When received within the cradle assembly, the substrate of the first BAVA is oriented perpendicular to the substrate of the second BAVA. The first BAVA is a vertical polarization input and the second BAVA is a horizontal polarization input.

An aperture of an antenna for a radar system comprises a first waveguide comprising a first protrusion and a second protrusion, each protrusion extending longitudinally along one side of the first waveguide. The aperture further comprises a second waveguide comprising a third protrusion and a fourth protrusion, each protrusion extending longitudinally along one side of the second waveguide. The first and third protrusions and second and fourth protrusions adjoin to form a radio frequency choke at least partially suppressing cross polarization of radio frequencies between the first and second waveguides.

A phased array antenna is made up of linear arrays. Each of the linear arrays has a printed circuit board spine. Split waveguides are formed from two symmetrical portions conductively joined to ground on opposite sides of the printed circuit board spine. Planar transmission line-to-waveguide transitions are mounted on the printed circuit board spine within the split waveguides. Phase shifter/TTD devices are mounted on the circuit board spine within the split waveguides for steering the phased array antenna beam. Bias and control circuitry is etched on the circuit board spine for biasing and controlling the phase shifter/TTD devices. The phased array antenna may be made up of the linear arrays combined into a two-dimensional array and fed with a waveguide feed or a printed feed manifold attached to the printed wiring board spine.
