Background
With the proliferation of mobile terminal usage, global mobile data traffic continues to grow at an unprecedented rate, and current 4G mobile network capacity will be unsustainable in the long term. One of the main differences of the 5G cellular system compared to the 4G system is the shift to the millimeter wave band, where a wider bandwidth is more easily obtained at higher frequency bands. Therefore, broadband millimeter wave device antennas, which are key devices in millimeter wave wireless systems, need to be designed and developed. Among various millimeter-wave antennas, the planar millimeter-wave array antenna has a great prospect due to the advantages of high gain and direct integration with a radio frequency front end. And in order to realize better signal transmitting and receiving capability, the millimeter wave array antenna is required to have wide coverage and multi-polarization performance, so that signals from any direction can be transmitted and received conveniently. Therefore, the millimeter wave planar integrated array antenna capable of radiating dual polarized waves has a good application prospect, and particularly is a miniaturized millimeter wave dual polarized planar integrated array antenna easy to directly integrate.
Magnetoelectric dipole antennas and arrays have gained much attention due to their characteristics of wide operating band, stable in-band gain flatness, stable unidirectional radiation patterns, and low cross polarization.

However, with regard to the design of the millimeter wave substrate integrated magnetoelectric dipole that has been reported so far, there are several aspects to be improved. Firstly, when most millimeter wave substrate integrated magnetoelectric dipoles are expanded into an array antenna, the bandwidth of the millimeter wave substrate integrated magnetoelectric dipoles is usually obviously narrowed; secondly, most millimeter wave substrate integrated magnetoelectric dipoles only realize single polarization or circular polarization performance, and the capacity of receiving information from different directions is limited; thirdly, most of feed networks of the millimeter wave substrate integrated magnetoelectric dipole antenna array adopt slot coupling feed, so that direct integration with a millimeter wave front end circuit chip is difficult to realize; in addition, the bandwidth of most millimeter wave dual-polarized substrate integrated magnetoelectric dipole array antennas is lower than 40%, and the space for improvement is still provided.
