Abstract:
1. A method for manufacturing an extruded slot antenna array, comprising: extruding a slot antenna body comprising a first major surface, a second major surface, first and second external side walls, and one or more longitudinally extending internal waveguide walls disposed between the first and second major surfaces, each internal waveguide wall forming a respective two or more open-ended waveguides, each open-ended waveguide comprising a first open end and a second open end; cutting an array of slots on the first major surface of the slot antenna body, the array of slots being arranged in a plurality of rows, each row arranged substantially along a longitudinal line of a respective open-ended waveguide; cutting a row of slots on the second major surface of the extruded slot antenna body, the row of slots aligned substantially perpendicular to the longitudinal axis of the open-ended waveguides, wherein the slots are distributed such that each open-ended waveguide comprises one of the slots; and attaching end caps to the first and second open-ends of each of the open-ended waveguides.
