Abstract
A grid-type microwave antenna comprises a multiplicity of generally parallel conductive rods. Each rod is curved along its length to form a section of a paraboloid so that when all the rods are positioned parallel to each other, in spaced apart relationship to each other, they form a paraboloidal reflector. A rim includes insulating members for receiving and holding the ends of the rods to position the rods in spaced apart and parallel relationship to each other.

A grid-type microwave antenna comprising
- a multiplicity of conductive rods, positioned parallel to each other in spaced apart relationship to each other, each of which is curved along its length to form a section of a paraboloid so that when all the rods are positioned parallel to each other in spaced apart relationship to each other, they form a paraboloidal reflector, and
- a rim including insulating strips for receiving and holding the ends of said rods to position the rods in spaced apart and parallel relationship to each other.
A method of assembling a grid-type microwave antenna having a paraboloidal reflector formed by an array of parallel conductive rods, said method comprising
- inserting said rods through an array of spaced holes in a first insulating strip extending orthogonally to said rods, so that when all the rods are positioned parallel to each other in spaced apart relationship to each other, they form a parabolic contour, the array of holes in said first insulating strip following the parabolic contour of said paraboloidal reflector,
- inserting the ends of said rods at one side of the array of parallel conductive rods through spaced holes in a second insulating strip and into a cavity formed by a first rim section, said second insulating strip being secured to said first rim section,
- inserting the ends of said rods at the other side of the array of parallel conductive rods through holes in a third insulating strip and into a cavity formed by a second rim section, said third insulating strip being fastened to said second rim section, and
- joining said first and second rim sections to each other and to said first insulating strip.
