A wideband dual-polarized magneto-electric (ME) dipole for millimeter wave band applications is presented. The ME dipole consists of four shorted patches, which are fed by two pairs of T-shaped probes orthogonally oriented on the same layer. The feed lines are connected with the T-shaped probes through metallic vias. Simulated overlapped impedance bandwidth of 50% with return loss larger than 10 dB, gain up to 9.4 dBi, and isolation higher than 17.8 dB between the dual polarizations are achieved. By combining the antenna elements with single-layered feed networks, a 2 x 2 array is designed, fabricated and measured. The overlapped working bandwidth is 50%, with gain up 14.8 dBi. With the advantages of wide bandwidth, single-layered radiation structure and promising radiation pattern, the proposed antenna with dual polarizations would be attractive for millimeter wave antenna in package (AiP) applications.
