Wideband slot-loop antennas for wireless communication systems
First Claim
1. An antenna comprising:
- (a) slot-loop structure having a generally planar loop element having a generally rectangular outer perimeter and a slot defining an inner perimeter of said structure, a mid portion of the slot-loop structure providing a major radiation portion of the antenna;
(b) a loading structure extending from one end of the slot, for top loading the radiation portion; and
(c) an impedance matching portion for coupling a feed to the major radiation portion.

Abstract
A wideband slot-loop antenna is described which comprises a generally planar loop element having a generally rectangular outer perimeter and a slot defining an inner perimeter, the mid portion of the slot-loop structure providing a major radiation portion of the antenna; a loading structure extending from one end of the slot, the loading structure for top loading the radiation portion; and an impedance matching portion for coupling a feed to the major radiation portion. The antenna also includes distributed matching patches. The distributed matching patches realize extra wideband performance. The antennas in the present invention are suitable for various wireless communications, such as PCS, Cellular Telephone, wireless data and computer network.
