Dual polarization planar array antenna and cell elements therefor
First Claim
1. A planar antenna array having a transmitting face and comprising a plurality of arrayed cells, each cell comprising:
- a first antenna probe;
a second antenna probe spaced away from the antenna; and
a reflector structure situated between the first and second antenna probes that is configured to pass RF waves transmitted/received by the second antenna probe and to reflect RF waves transmitted/received by the first antenna probe

Abstract
An RF antenna structure (e.g., a planar array) includes at least one radiation cell (and typically many, e.g., 16 or 32 or 64, etc.) having a conductive enclosure and an upper probe and a lower probe located at different heights within the enclosure. The enclosure between the upper probe and a bottom of the cell has at least two different cross-sectional areas. The upper and lower probes are preferably oriented at substantially 90° relative to each other. An upper portion of the enclosure beneath the upper probe may have a larger dimension than a lower portion such that the upper portion allows propagation of waves generated by the upper probe in a predetermined frequency band while the lower portion (e.g., above the lower probe) does not substantially allow propagation of waves generated by the upper probe, in the predetermined frequency band.
