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 with at least two separate slots; and
(ii) an electrically-conductive metal cover mounted directly 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, directly and unassisted by any intermediary element, by the at least two separate slots in conjunction with the millimeter waves radiated, 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.

23. A method for producing a millimeter-wave antenna system, comprising:
-
forming at least two separate slots in an electrically-conductive lamina of a printed-circuit-board, said at least two separate slots are operative to radiate millimeter-waves, and said at least two separate slots are located in respect to each other such as to facilitate, in conjunction with the millimeter-waves radiated, direct synthesis of a millimeter-wave radiation pattern, in which said direct synthesis is unassisted by any intermediary element; and mounting, directly on top of said electrically-conductive lamina, an electrically-conductive metal cover, such that an enclosed wave-guide cavity is formed above said at least two separate slots, thereby forming a first slotted wave-guide operative to function as a millimeter-wave antenna system. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)
