Abstract:
1. A circularly-polarized micropatch antenna comprising: a radiating element comprising a first rectangular region having a first edge, a second edge, a third edge, and a fourth edge, wherein: a ground plane comprising a second rectangular region having a fifth edge, a sixth edge, a seventh edge, and an eighth edge, wherein: an air gap between said radiating element and said ground plane; and a plurality of capacitive elements consisting of: wherein: no capacitive elements are disposed on said radiating element within said first rectangular region; no capacitive elements are disposed on said ground plane within said second rectangular region; said first edge and said second edge have a first length; said third edge and said fourth edge have a second length; said fifth edge and said sixth edge have a third length; said seventh edge and said eighth edge have a fourth length; said third length is greater than said first length; said fourth length is greater than said second length; said first straight series of localized structures, said second straight series of localized structures, said third straight series of localized structures, and said fourth series of localized structures are located at least in part within a region between said fifth straight series of localized structures, said sixth straight series of localized structures, said seventh straight series of localized structures, and said eighth straight series of localized structures; said first straight series of localized structures is aligned with said fifth straight series of localized structures; said second straight series of localized structures is aligned with said sixth straight series of localized structures; said third straight series of localized structures is aligned with said seventh straight series of localized structures; and said fourth straight series of localized structures is aligned with said eighth straight series of localized structures.
