MILLIMETER-WAVE SLOT ANTENNA SYSTEMS AND METHODS WITH IMPROVED GAIN
First Claim
1. A millimeter-wave antenna system comprising:
- a first slotted wave-guide operative to transport millimeter-waves comprising;
(i) a printed-circuit-board comprising an electrically-conductive lamina mounted on a substrate lamina, said electrically-conductive lamina is cut accurately with at least two separate slots; and
(ii) an electrically-conductive metal cover mounted on said electrically-conductive lamina, such that an enclosed wave-guide cavity is formed above said at least two separate slots, thereby forming said first slotted wave-guide;
wherein said first slotted wave-guide is operative to guide millimeter-waves over said at least two separate slots, thereby radiating millimeter-waves via said at least two separate slots, thereby forming a predetermined millimeter-wave radiation pattern.

Abstract
Various embodiments of a millimeter-wave antenna system configured to enhance the gain in a communication network, in which one or more slotted wave-guides produce radiating slot structures that form accurate high-gain millimeter-wave radiation patterns. The system comprises one or more slotted wave-guides to transport millimeter-waves, a PCB including a substrate lamina and an electrically-conductive lamina with two or more highly accurate slots, and an electrically-conductive metal cover that intersects the electrically-conductive lamina to form an enclosed wave-guide cavity. Various embodiments of methods for producing the millimeter-wave antenna system, including different techniques for creating the accuracy of the slots in the slotted wave-guides.
