Dual-Band Wide-Angle Scanning Phased Array Composed of Stacked Patch Antennas

In this paper, a probe-fed stacked patch antenna as dual-band wide-angle phased array element is designed. Antenna element and 1×11 finite array are studied in simulation, respectively. The proposed antenna element operates at 5.44 GHz and 6.65 GHz, and the 3dB-beamwidth of the element in finite array is wider than 160° in E-plane at both frequencies. The proposed array enables the ability to scan up to 70° at both frequencies. The proposed phased array antenna shows the advantages of dual-band, wide-scanning angle and good polarization purity.
