Abstract
Abstract An integrated function microwave radiating structure capable of radiating electromagnetic energy at several selectively predetermined different frequency bands simultaneously and which can be used as an element of a large microwave array antenna is disclosed. The unitary substantially rectangular structure comprises multiple, closely spaced sets of radiating elements of various possible configurations located and supported in a defined aperture area in an interlaced contiguous manner with respect to each other. Each set of radiating elements radiates over a particular frequency band within the total band over which coverage is required. By energizing each radiating element independently in a predetermined phase and amplitude relationship with respect to the other elements, the radiated composite beam (from each of the elements) can be scanned in either the horizontal or vertical planes. Undesired mutual interaction affects between the closely spaced adjacent elements operating at different frequencies are minimized by cross-polarizing techniques.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
164 words
An integrated function antenna array structure comprising: a plurality of columns of vertically polarized, C-band rectangular waveguides and X-band rectangular waveguides; each of said X-band waveguides in each of said columns being disposed and rigidly supported in a contiguous, face-to-face stacked relationship between two of said C-band waveguides; a plurality of columns of horizontally polarized, S-band rectangular waveguides; said S-band waveguides in each of said columns being disposed and rigidly supported in a contiguous, end-to-end stacked relationship with respect to each other; each of said columns of C-band and X-band waveguides being disposed and rigidly supported in a contiguous manner between two of said columns of S-band waveguides; whereby all of said columns of C-band, X-band and S-band rectangular waveguides comprise a substantially rectangular, unitary antenna structure; and electromagnetic energy source means connected to each of said C-band, X-band, and S-band waveguides at the closed end thereof in an end-fed manner whereby each of said waveguides can be energized independently of the other waveguides.
Claim 2
Dependent Claim
164 words
An integrated function antenna array structure comprising: a plurality of columns of vertically polarized, C-band rectangular waveguides and X-band rectangular waveguides; each of said X-band waveguides in each of said columns being disposed and rigidly supported in a contiguous, face-to-face stacked relationship between two of said C-band waveguides; a plurality of columns of horizontally polarized, S-band rectangular waveguides; said S-band waveguides in each of said columns being disposed and rigidly supported in a contiguous, end-to-end stacked relationship with respect to each other; each of said columns of C-band and X-band waveguides being disposed and rigidly supported in a contiguous manner between two of said columns of S-band waveguides; whereby all of said columns of C-band, X-band and S-band rectangular waveguides comprise a substantially rectangular, unitary antenna structure; and electromagnetic energy source means connected to each of said C-band, X-band, and S-band waveguides at the closed end thereof in an end-fed manner whereby each of said waveguides can be energized independently of the other waveguides.
