Abstract

Abstract There is disclosed an antenna structure utilizing a loop having an annular ring coupled thereto and lying in a substantially horizontal plane transverse to the plane of the loop. The ring has reflector and director elements mounted thereon, and on opposite sides of the ring to offer increased directivity to the structure. A pair of dipoles are also utilized in the antenna structure. The dipoles are mounted on a first rotatable base assembly and the loop is mounted on a second rotatable base assembly. These base assemblies are rotatable with respect to a fixed base member and are controlled in rotation by means of a knob to permit azimuth orientation of the antennas.

An antenna structure, comprising: a. a loop of a given configuration, b. an annular ring coupled to said loop and lying in a substantially horizontal plane transverse to the plane containing said loop, and c. at least one beam shaping element mounted on said annular ring and extending along a portion of the surface thereof to provide increased directivity for said antenna.
Claim 2
Dependent Claim 62 words
An antenna structure, comprising: a. a loop of a given configuration, b. an annular ring coupled to said loop and lying in a substantially horizontal plane transverse to the plane containing said loop, and c. at least one beam shaping element mounted on said annular ring and extending along a portion of the surface thereof to provide increased directivity for said antenna.
Claim 3
Dependent Claim 21 words
The antenna according to claim 1 wherein said beam shaping element is of a serpentine configuration fabricated from a conducting metal.
Claim 4
Dependent Claim 26 words
The antenna according to claim 1 wherein said beam shaping element is of an arcuate configuration fabricated from a conducting metal located on a surface thereof.
