A Millimeter-wave Aperture-coupled Simple Low-Profile Magneto-Electric Antenna

A millimeter-wave low-profile magneto-electric(ME) dipole antenna is presented in this paper. The proposed ME dipole antenna is designed on two pieces of substrate with different materials and fed by aperture-coupled technique. Unlike the previously reported ME dipole antennas, there is no verticalcavity serving as a magnetic dipole in this design, while the magnetic dipole is formed by the gap between the two horizontal patches, this design makes the geometry of the ME dipole antenna simple acid easy to be fabricated. Simulated results show that the proposed ME dipole has impedance bandwidth (VSWR≤2) of 29.1% from 23.5 GHz - 31.5 GHz and a stable high gain of 8.3 ± 0.7 dBi across the operating frequency band.
