Abstract
Abstract The antenna assembly is formed by building a shell housing by punch press operation. The housing contains the antenna features. The dielecric with load and connector is placed into the housing. Then a back is placed onto the assembly and the unit is enclosed by laser welding. This design allows the fabrication of the housing to be constructed with the antenna features built in and is simpler and less costly than prior designs.

Claim 1
Independent Claim
107 words
An antenna assembly comprising: a dielectric substrate which is composed of dielectric materials and which serves as an antenna element in said antenna assembly, said dielectric substrate having a metallic electrical connector protruding out of one end; a foil formed waveguide housing which is punch pressed from foil materials including aluminum and stainless steel foils to form a waveguide channel which fits over said dielectric substrate; and a base plate which is fixed to said foil formed waveguide housing to encapsulate said dielectric substrate, said base plate having an aperture which permits said metallic electrical connector from said dielectric substrate to extend out of said antenna assembly.
