摘要：
In this letter, we report the results of an investigation of multimode microstrip patch resonators and their applications for designing dual-polarized wide-angle scanning phased arrays. The proposed multimode patch element can provide broadside (TM01 or TM10 modes) and monopole-like (TM21 mode) patterns which are combined to obtain a joint wide-beam coverage in both xoz and yoz planes. By interactively selecting these modes, the formed 8 x 8 planar phased array can scan its main beam from -64 degrees to+ 64 degrees in the two orthogonal planes. Measured results validate some notable features, such as the dual-plane wide-angle scan with the same polarization and high realized gain with low sidelobe levels.
