A Millimeter-Wave Ultra-Low Profile Dual-Polarization Antenna and Its Phased Array Design for Terminal Applications
Year: 2026
Type: conference-paper
Abstract: This paper presents 1 × 4 phased array based on a ultra-low profile dual-polarization patch antenna with enhanced bandwidth for millimeter-wave terminal applications. The bandwidth is extended by using a single-layer radiating patch fed by closely positioned microstrip resonators and C-shaped resonators, which achieves the low-profile characteristic. Simulation results of the element reveal an operating bandwidth of 24.42–24.79 GHz (a fractional bandwidth of 13.0%) and 24.02– 28.51 GHz (a fractional bandwidth of 17.3%) for horizontal- polarization and vertical-polarization, respectively. Measurement results of beam scanning shows a ±45° scan coverage, with 20 dB cross-polarization suppression within the main lobe at each scan angle.
