Abstract
Abstract A dual polarized printed circuit antenna operating in dual frequency bands. A first array (3) of radiating elements radiates at a first frequency, and a second array (5) of radiating elements radiates at a second, different frequency. Separate power divider arrays (2, 4) are provided for each array of radiating elements, and the overall structure is provided in a stacked configuration. <IMAGE>

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
112 words
In a dual polarized printed antenna comprising a ground plane, a first power divider array disposed over said ground plane, a first array of radiating elements disposed over said power divider array, and second power divider array disposed over said first array of radiating elements, and a second array of radiating elements disposed over said second power divider array, the improvement wherein said first array of radiating elements comprises an array of radiating elements so configured as to operate at a first frequency, and said second array of radiating elements comprises an array of radiating elements so configured as to operate at a second frequency that is different from said first frequency.
Claim 2
Dependent Claim
17 words
An antenna as claimed in claim 1, wherein said second frequency is lower than said first frequency.
Claim 3
Dependent Claim
36 words
An antenna as claimed in claim 2, wherein said first and second power divider arrays comprise respective power divider arrays for feeding said first and second arrays of radiating elements at said first and second frequencies.
Claim 4
Dependent Claim
27 words
An antenna as claimed in claim 1, wherein elements in said first array of radiating elements are smaller than elements in said second array of radiating elements.
Claim 5
Dependent Claim
45 words
An antenna as claimed in claim 1, wherein said first and second power divider arrays comprise tee junctions and impedance transforming sections, the impedance transforming sections of said second power divider array being longer than the impedance transforming sections of said first power divider array.
