In this paper, a novel microstrip phased array with dual-polarized and wide-angle scanning in the 2-dimensional (2D) space is proposed. The element antenna consists of a mushroom-shaped patch and two circular patches. Each circular patch is connected with one feeding port. The mushroom-shaped patch is excited via capacitive coupling through the gaps between the mushroom-shaped patch and the circular patch. The zeroth-order resonance (ZOR) and TM010 mode resonance are simultaneously generated in the mushroom-shaped patch. The 3dB beamwidth of the element antenna in the 2D space is in the range between 110° and 125°. One 6×6 phased array based on the antenna element is designed, fabricated and measured. The phased array shows dual-polarized wide-angle beam scanning in a range of ±66° in both x-z and y-z planes with the scan loss of 3.5dB.
