A Broadband Millimeter-Wave Antenna-in-Package Made of Low-Profile Magnetoelectric Dipole

This paper presents a broadband millimeter-wave planar magnetoelectric (ME) dipole antenna. By intro-ducing an E-shaped feeding branch underneath the main radiating patch, a broadband ME dipole antenna with an ultra-low profile of
$0.086\lambda_{0}$
(where
$\lambda_{0}$
represents the free-space) is obtained. A simulated impedance bandwidth of 19.3% (23.4-28.4 GHz) is obtained from the proposed antenna. Across the impedance bandwidth, the ME dipole also shows good radiation characteristics.
