Abstract
Abstract A reflector for high gain antennae comprising a plurality of generally triangular shaped petals joined in edgewise overlapping relation, wherein the overlap gradually increases from rim to center of the reflector, so as to provide a mechanically stable paraboloid configuration. The petals are supported by a rigid rim structure constructed of preformed tubular sections.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
93 words
In a reflector for high-gain antennae having a plurality of generally planar, triangular electromagnetically reflection petals having a longitudinal axis and rectilinear longitudinal edges, means for connecting adjacent petals in longitudinal edgewise overlapping relation through holes therein at predetermined locations to form a reflector having the shape of a surface of revolution, each petal taking the form along its longitudinal axis of the line that generates the surface of revolutions and having generally curvilinear transverse form, the improvement comprising gradually increasing the overlap of adjacent petals from rim to center of the reflector.
Claim 2
Dependent Claim
93 words
In a reflector for high-gain antennae having a plurality of generally planar, triangular electromagnetically reflection petals having a longitudinal axis and rectilinear longitudinal edges, means for connecting adjacent petals in longitudinal edgewise overlapping relation through holes therein at predetermined locations to form a reflector having the shape of a surface of revolution, each petal taking the form along its longitudinal axis of the line that generates the surface of revolutions and having generally curvilinear transverse form, the improvement comprising gradually increasing the overlap of adjacent petals from rim to center of the reflector.
Claim 3
Dependent Claim
34 words
In the reflector of claim 1, the improvement further including holes located along a rectilinear centerline nearer the longitudinal edges of the petals at the wide end thereof than at the narrow end thereof.
Claim 4
Dependent Claim
41 words
In the reflector of claims 1 or 2, the improvement further including a segmented, tubular rigid rim coupled to the wide ends of the petals, each tubular rim segment being bent to a preselected angle determined by the number of petals.
Claim 5
Dependent Claim
29 words
In the reflector of claim 3, the improvement further including tubular rim segment having an enlarged end to receive the other end of a substantially identical tubular rim segment.
