Abstract: A dual-polarized antenna array includes at least one Balanced Antipodal Vivaldi Antenna (BAVA) element pair. A particular pair of the at least one BAVA element pair includes a first BAVA and a second BAVA. A substrate of the first BAVA forms a notched portion along a center axis of the first BAVA. A substrate of the second BAVA forms a notched portion along a center axis of the second BAVA. Each BAVA of the particular BAVA element pair includes a plurality of conductors. The notched portion of the substrate of the first BAVA is received by the notched portion of the substrate of the second BAVA, and the notched portion of the substrate of the second BAVA is received by the notched portion of the substrate of the first BAVA. The substrate of the first BAVA is in an orthogonal orientation relative to the substrate of the second BAVA.

Abstract: 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.

Abstract: The present disclosure provides a radiating element, such as a Balanced Antipodal Tapered Slot Antenna (BAVA) radiating element having embedded circuitry which includes an integrated filter and functions as a port mismatch circuit for protecting a communication system implementing the radiating element from jammers. The embedded circuitry may provide a dynamically adjustable filter and/or a port mismatch circuit at the radiating element level which allows for center frequency tuning, provides selectivity and/or acts as an adaptive first line of defense layer for protecting sensitive radio and digital signal processing (DSP) physical layers of the communication system.

Abstract: The present disclosure is directed to a dual polarized antenna array including a first BAVA (a horizontal polarization input), a second BAVA (a vertical polarization input), and a cradle assembly. The substrates of the first and second BAVAs each include a notched portion. The cradle assembly includes a base plate having four channel modules connected thereto. Edge portions of the substrates of the first and second BAVAs are received by the cradle assembly via channels of the channel modules and apertures of the base plate. The substrates of the BAVAs are interleaved via their notched portions so that the substrate of the second BAVA is an orthogonal orientation relative to the substrate of the first BAVA.
