Wideband ± 45° Dual-polarized Magnetoelectric Dipole Antenna with Stable Wide Beamwidth

A wideband ± 45° dual-polarized magnetoelectric dipole antenna is proposed in this paper. Placed on aluminum plate and fed by two L-shaped feeding lines, the proposed antenna can provide a wide bandwidth with satisfactory radiation properties. By bending the antenna arm, the current distribution of the vertical parasitic structure is increased, and then the radiation of the vertical parasitic structure is increased. The antenna achieved a wide impedance bandwidth of about 45.4% for
$\text{VSWR} < 1.75$
at both ports, covering the frequency range from 1.7 to 2.7GHz. Over the operating frequency, a gain>5.3dBi is achieved for both ports. The isolation between the two ports is larger than 28dB. The results show a stable radiation pattern with the half-power beamwidth
$95^{\circ}\pm 5.5^{\circ}$
at H-plane and V-plane.
