Abstract

An antenna having a plurality of antenna elements formed into a conductive layer engaged upon a planar dialectic is disclosed. The plurality of formed elements provide for reception and transmission of RF energy in both horizontal and vertical polarized orientations as well as at angles therebetween.

Claims

1. An antenna element, comprising:

a planar dialectic material having opposing first and second sides;

a rectangular planar conductive material operatively engaged to one of said two sides;

said planar conductive material having a preferred vertical orientation having a first horizontal edge and parallel second horizontal edge spaced therefrom;

first and second side edges vertically disposed between said first and second horizontal edges;

a first cavity formed in said conductive material, said first cavity having a mouth portion extending between two points along said second horizontal edge;

a first side edge of said first cavity extending in a line from one side of said mouth substantially parallel to said first and second side edges;

a second side edge of said first cavity extending in curved line from an opposite side of said mouth as said first side edge;

said first and second side edges defining a said cavity declining in cross section from a widest point at said mouth;

a second cavity formed in said conductive material, said second cavity having a mouth portion extending between two points along one of said side edges;

a first side edge of said second cavity extending in a line from one side of said mouth substantially perpendicular to said first side edge of said first cavity;

a second side edge of said second cavity extending in curved line from an opposite side of said mouth as said first side edge of said second cavity;

said first and second side edges said cavity as declining in cross section from a widest point at said mouth thereof; and

a feed line operatively engaged with said conductive material whereby RF signals may be received by said antenna element in horizontal and vertical polarizations, and at angles therebetween between respective first and second side edges of said first and second cavities.

2. The antenna element of claim 1 additionally comprising:

a serpentine cavity formed in said conductive material extending from at least one of said side edges;

said serpentine cavity defining a meanderline antenna element of said antenna element.

3. The antenna element of claim 1 additionally comprising:

two curvilinear cavities in a mirrored configuration extending from a side edge of said conductive material;

both said curvilineal cavities defined by two parallel side edges extending in a curved path; and

said parallel side edges of each respective side edge separated from the respective other by a distance, said distance defining an RF frequency for reception by a third antenna and fourth antenna element formed by said curvilineal cavities.

4. The antenna element of claim 2 additionally comprising:

two curvilinear cavities in a mirrored configuration extending from a side edge of said conductive material;

both said curvilineal cavities defined by two parallel side edges extending in a curved path; and

said parallel side edges of each respective side edge separated from the respective other by a distance, said distance defining an RF frequency for reception by a third antenna and fourth antenna element formed by said curvilineal cavities.

5. The antenna element of claim 1 additionally comprising:

a planar ground plane formed by said conductive material running in a plane normal to an adjacently positioned first horizontal edge.

6. The antenna element of claim 2 additionally comprising:

a planar ground plane formed by said conductive material running in a plane normal to an adjacently positioned first horizontal edge.

7. The antenna element of claim 3 additionally comprising:

a planar ground plane formed by said conductive material running in a plane normal to an adjacently positioned first horizontal edge.

8. The antenna element of claim 4 additionally comprising:

a planar ground plane formed by said conductive material running in a plane normal to an adjacently positioned first horizontal edge.
