US Patent:

40865975, Apr 25, 1978

Filed:

Dec 20, 1976

Appl. No.:

5/752657

Inventors:

Allen I. Sinsky - Baltimore MD
Paul C. Wang - Baltimore MD
Robert E. Willey - Baltimore MD

Assignee:

The Bendix Corporation - Southfield MI

International Classification:

H01Q 1906

US Classification:

343754

Abstract:

In a microwave lens of the Rotman type for a scanning beam antenna a plurality of radiating feed probes are spaced along the focal arc. An illumination function is then commutated around the focal arc by energizing groups of the feed probes simultaneously in accordance with weighting functions to thereby cause the resulting radiated beam to scan in small equally spaced increments while the array factor remains essentially constant. Methods of calculating the weighting functions and feed probe spacing are shown.

Abstract:

An antenna feed network is described incorporating a plurality of power dividers and a plurality of power combiners to distribute at least two microwave signals over predetermined electrical path lengths to two overlapping subarrays of antenna elements forming an antenna aperture. The invention further provides a module incorporating a plurality of power dividers and power combiners utilizing Wilkenson strip-line power dividers and utilizing zero db branch arm hybrid couplers to provide wiring crossovers on the upper surface of a printed circuit board having a ground plane on its lower surface.
