ABSTRACT:
A phased array antenna system including a plurality of metal, column-like elements formed adjacent the RF probes for improving the electrical performance of the system. In one embodiment a hole is formed in a multi-layer, probe-integrated printed wiring board of the system and metal material is plated thereon to fill the hole. The metal, column-like elements are each disposed generally in between associated pairs of the RF probes. The metal, column-like elements essentially form metal pins that improve the return loss bandwidth, probe-to-probe isolation, insertion loss bandwidth, higher order mode suppression and cross-polarization generation.
