Design and Analysis of a Novel Wide-Angle Scanning Stub-Loaded Cavity Array Element

Abstract: A novel design methodology is presented to mitigate scan blindness in cavity antenna arrays without the need for any changes on the radiating structure itself. For a first proof-of-concept demonstration, a fully PCB-compliant dual-polarized cavity element is loaded by vertical stubs to manipulate the dispersion characteristics in the aperture plane. In contrast with its conventional cavity antenna counterpart, the proposed stub-loaded unit cell element shows through scattering and eigenmode analysis that the v… Show more
