Filed:

Jan 8, 1987

Appl. No.:

7/001284

Inventors:

Oscar M. Garay - North Lauderdale FL

International Classification:

H01Q 138

US Classification:

343700MS

Abstract:

A laminar antenna includes a conductive ground plane (102), a first dielectric lamina (106), a conductive exciter lamina (108), a second dielectric lamina (114), and a conductive radiator lamina (116). The radiator partially overlaps the exciter and the amount of overlap determines the input impedance of the antenna. The laminar antenna can be positioned within the wall of a plastic radio housing (302). Multi-radiator wideband and duplex embodiments of the antenna are also described. In another embodiment, the ground plane extends above the radio housing while the radiator and dielectric laminae wrap around the extended portion of the ground plane.

Abstract:

A multi-resonant antenna is formed by a plurality of resonators which resonate at different frequencies. A feed member is coupled to the multi-resonant resonators. Disposed between and separating the resonators from the feed member is a dielectric substrate.
