An improved microwave radar antenna including a plurality of linear waveguides arranged in a two dimensional array with each linear waveguide having a mounting flange along the bottom narrow edge of the waveguide for attachment to the ground plane of the antenna by the conductive epoxy. Also disclosed is a method of manufacturing an improved microwave antenna where flanged linear waveguides are milled to provide for radiator slots and then are affixed to a attentive ground plane along the flanged edge of the waveguide by a conductive epoxy.

Microwave radar antenna and method of manufacture

An improved vapor phase soldering process and apparatus are disclosed having particular application to electronic circuitry designed for operation at frequencies higher than 1 MHz. A printed circuit board having a defined circuit pattern on both sides is clamped between two parallel clamping fixtures, one having circuit matching characteristics for the specified PC board, and the fixture further having vents allowing vapor phase gas access to the PC board and soldering process waste gasses egress from the soldering area. This process and apparatus allows shortened soldering time, and improves performance characteristics of the PC board by improving the conduction characteristics of the defined circuit pattern.
