Abstract

This paper describes the development of a multilayer dual-band dual-polarized antenna operating at L and C bands with a common aperture. Unlike earlier approaches, slot coupled patches are employed at both bands to reach cross-polarization suppression better than 30 dB. The antenna has been conceived to be used as a basic module in large series-fed arrays featuring light weight, high efficiency and beam scanning. Moreover, by properly scaling the geometry, the antenna can operate at any else pairs of frequencies with a ratio between 3.5-4.5.
