Abstract

An antenna comprising a substrate having a pair of oppositely directed surfaces. A source plane conductor is located on one of the surfaces and has a signal line connected thereto. A ground plane conductor is located on another of the surfaces. Each of the conductors has a slot extending therethrough with said slots sized and positioned relative to one another to inhibit the intensity of radiation emanating from the ground plane.

Claims (11)

Claims:
1. An antenna comprising a substrate having a pair of oppositely directed surfaces, a source plane conductor on one of said surfaces having a signal line connected thereto, a ground plane conductor on another of said surfaces, each of said conductors having a slot extending therethrough with said slots sized and positioned relative to one another to inhibit the intensity of radiation emanating from said ground plane.
2. An antenna according to claim 1 wherein each of said slots extend from a peripheral edge of said substrate.
3. An antenna according to claim 2 wherein one of said slots is L shaped.
4. An antenna according to claim 3 wherein both of said slots is L shaped.
5. An antenna according to claim 2 wherein each of said slots has an axial leg extending on a longitudinal axis of said antenna and a transverse leg extending from said peripheral edge to intersect said axial leg.
6. An antenna according to claim 5 wherein said axial legs are aligned on each of said planes.
7. An antenna according to claim 5 wherein said transverse legs are aligned on each of said planes.
3. An antenna according to claim 3 wherein one of said slots is formed as an H with an intermediate leg extending to a peripheral edge.
9. An antenna according to claim 1 wherein the length of the slot in the source plane is between 1.46 and 1.36 that of the slot in the ground plane.
10. An antenna according to claim 1 wherein the length of the slot in the source plane is between 1.60 and 1.51 that of the slot in the ground plane.
11. An antenna according to claim 1 wherein the length of the slot in the source plane is between 3.0 and 3.04 that of the slot in the ground plane.
