Patent attributes
A reflect array antenna including a plurality of unit cells. Each cell includes first, second, third and fourth patch antenna segments. An amplifier is coupled between said first patch segment and the second patch segment or the third patch segment and the fourth patch segment. At least one of the patch antenna segments of a first unit cell is electrically connected to a patch antenna segment of a second unit cell. The first patch antenna segment of a first unit cell is electrically connected to a third patch segment of a second unit cell. Each patch segment of each unit cell is electrically connected to a patch segment of a neighboring cell. The first and third patche segments are the input terminals of each cell and the second and fourth patch segments of each cell are the output terminals. The output terminals of each cell are coupled to the output terminals of neighboring cells. This provides an output patch antenna, of greater area, fed by multiple cells.
