High-gain Dual-Polarized SIW Shared Aperture Magnetoelectric Dipoles Antenna Array

In this paper, a high-gain dual-polarized shared aperture magnetoelectric dipole (MED) antenna with substrate-integrated waveguide (SIW) as feed network is proposed. The antenna element effective size is
$0.48 \lambda_{0} \times 0.48 \lambda_{0} \times 0.2 \lambda_{0}$
. A bandwidth of 14% (36.4GHz-41.9GHz) for
$\vert \mathrm{S}11\vert < -10\text{dB}$
can achieved. Antenna radiation pattern is superior, and it has unidirectional radiation. The peak gain of the antenna is 9.35dB, and the average gain is 8.65dBi. A
$2\times 2$
square array can be created by grouping the proposed MED antenna element. By adjusting the phase of each port, the four-beam radiation mode is realized. Based on the advantages of antenna radiation performance, it is conducive to processing and integration, and can be applied to wireless communication system.
