1. A laminar antenna, comprising in combination:
- a substantially flat conductive ground plane lamina having first and second surfaces;
a first dielectric lamina superposed said first surface, wrapping around an end of said ground plane lamina, and superposing a portion of said second surface of said ground plane lamina;
a second dielectric lamina superposed said first dielectric lamina, and extending over said first surface of said ground plane lamina, wrapping around said end of said ground plane lamina and extending over said second surface of said ground plane lamina;
a conductive exciter lamina positioned between said first and second dielectric laminae; and
a radiator lamina superposed said second dielectric lamina and extending over said first surface of said ground plane lamina, wrapping around said end of said ground plane lamina and extending over a portion of said second surface of said ground plane lamina.

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.
