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 ()
