Dual-polarized, x-band, flat-panel phased array

A stacked-patch, broadband, dual-polarized, aperture-fed antenna is designed with a center frequency of 10 GHz and a bandwidth greater than 3 GHz. This antenna is then used in a four element array configuration which utilizes digital phase-shifters, controlled by LabVIEW, to steer the beam. The dual-polarized array can provide a ±45° scan angle over a 3 GHz bandwidth.
