ABSTRACT:
Disclosed herein is a front-end device for a phased array system. The front-end device includes an array of horn antennas, a first set of transmission lines coupled to the horn antenna array for a first polarization, a second set of transmission lines coupled to the horn antenna array for a second polarization orthogonal to the first polarization, and a plurality of L-shaped excitation elements. Each L-shaped excitation element of the plurality of L-shaped excitation elements couples a transmission line from each of the first and second sets of transmission lines to a respective horn antenna of the horn antenna array.
