This paper introduces wideband dual polarized stacked suspended plate antenna operating in 1710-2170 Mhz. Antenna consists of two pairs of stacked suspended plate antennas, which have novel capacitively coupled feeding probes different than excitation of classical patch antennas. Antenna is designed to provide independent +/- 45 degrees linearly polarized dual channels for polarization diversity. Antenna elements of these +/- 45 degrees channels are separated by a distance in azimuth and interleaved by a distance in elevation to have a good isolation between ports. Starting from single element, antenna is designed, simulated, manufactured and measured. Simulations are in good agreement with the measurement in terms of antenna performance parameters; return losses, channel isolation, radiation patterns and gain.
