Modal significances for the same rectangular patch but with different dielectric substrate and ground plane configurations.
(a) Modal significances for isolated rectangular patch in free space |
(b) Modal significances for rectangular patch with ground plane. The space between the patch and the ground plane is filled with air () |
(c) Modal significances for rectangular patch with grounded dielectric substrate () |
