Design of Dual-Band Dual-Polarization Millimeter-Wave Stacked Dielectric Resonator Antenna

This paper presents a dual-band dual-polarization stacked dielectric resonator antenna (DRA) element design. Two mutually perpendicular bonding wire structures are used for realizing wide bandwidth feeding network. The DRA is implemented in low-cost integrated passive device (IPD) envirnoment. This millimeter wave DRA exhibits wide bandwidth, wide beamwidth and high gain characteristics. It is suitable for dual polarized millimeter wave scanning antenna array system application.
