摘要：
A wideband magneto-electric (ME) dipole array antenna fed by substrate integrated waveguide (SIW) is proposed in this paper. By combining the bowtie-shaped slot on the top surface of the SIW as a magneto dipole, and a shorted patch as an electric dipole, the ME-dipole element is realized. Then a 1x8 array operating at 28GHz is formed with eight ME-dipole elements and a wideband SIW feed network. Simulation results show that the array antenna can achieve an impedance bandwidth of 31.4% (24.2-33GHz) and a peak gain of 14dB. Moreover, stable radiation patterns, low cross-polarization levels and low front-to-back ratio are obtained over the wide band, which makes the proposed antenna a good candidate for the 5G millimeter-wave wireless communication system.
