First Claim
Patent Images
1. A drooping helix antenna comprising:
- at least first and second radiating elements of conductive material, each element extending in a first direction in a first plane and having a portion thereof drooping in at least a second direction in a second plane;
means for individually feeding at least two of said elements; and
means for maintaining said radiating elements in a substantially helical or spiral shape except for said drooping portion.

Abstract
A drooping quadrifilar helix antenna includes first, second, third, and fourth radiating elements (42, 44, 46, and 48 respectively) of conductive material, each element extending in a first direction in a first plane and at least one of the radiating elements having a portion (47) thereof drooping in a second direction in a second plane, the antenna further including a dielectric tube (45) for maintaining a substantial portion of the radiating elements in a substantially helical or spiral shape, a coupler (24) for coupling electrical energy to and/or from each of said radiating elements, and a feed network (22) for individually feeding at least two of the radiating elements.
