Abstract
A microstrip feeds a patch antenna through a slot in a two part RF ground plane. The dual RF ground planes permit DC control of a varactor positioned over a slot in the ground planes while maintaining a high degree of AC coupling between the two planes. The AC coupling between the two ground planes is increased by increasing the capacitive coupling between the planes using an interlocking finger pattern.
