Abstract

A flat strip-like radiator is angled along the width of the strip to form radiating arms of predetermined length and angles to radiate a design radiation patter. The flat strip is secured to a ground plane such that the flat strip is perpendicular to the ground plane.

Claims

1. A traveling wire antenna which comprises:

a substantially planar ground plane;

at least one insulator;

a flat strip-like radiator having a width and a length spaced above the ground plane, the plane in which the flat strip-like radiator lies being substantially parallel to the ground plane, the flat strip-like radiator being electrically isolated from the ground plane and supported by the insulator, the width of the flat-strip like radiator being substantially perpendicular to the ground plane, the radiator comprising a plurality of arms sequentially joined at their ends to define an angular relationship between adjacent arms, the length of the arms and the angles at which the arms are joined to one another, together provide a desired radiation pattern; and

means for feeding power to the radiator.

2. The antenna of claim 1 wherein the radiator is configured to provide a 65°

radiation pattern.

3. The antenna of claim 2 which comprises at least one radiator.

4. The antenna of claim 1 wherein the radiator is configured to provide a 30°

radiation pattern.

5. The antenna of claim 4 which comprises at least two radiators.

6. A method of making a traveling wire antenna which comprises:

bending a flat strip-like material having a length and a width at predetermined lengths and angles;

securing the flat strip-like material onto a least one insulator and spaced above a ground plane, the flat strip-like material being supported by the insulator and substantially parallel to the ground plane and the width of the flat strip-like material being substantially perpendicular to the ground plane whereby when power is fed to the radiator the desired radiation pattern will be provided.

7. The method of claim 6 which comprises:

maintaining the radiators in spaced apart relationship from the ground plane by insulators.
