ABSTRACT:
An improved serpentine feed and method of making same. The invention includes a block of conductive material having a primary microwave waveguide channel and at least one secondary channel. Each secondary channel has at least one broadwall common to the primary channel. A high performance coupler is provided in the common broadwall by which microwave energy communicates from the primary channel to the secondary channel. The claimed method of the invention includes the steps of (a) machining mating halves of a first elongated channel into first and second blocks of conductive material; then, (b) machining mating halves of a plurality of second channels into the first and second blocks longitudinally parallel with at least a portion of the halves of the first channel thereby providing a plurality of common broadwalls between the first channel and each of the second channels; next, (c) machining a plurality of slots in each of the common broadwalls between selective first and second channels; and finally, (d) either mechanically fastening or bonding the first and second blocks in alignment such that halves of the first and second channels mate to provide primary and secondary microwave waveguides respectively.
