The international telecommunications union ITU identified three major application scenarios for 5G at ITU-RWP5D meeting No. 22 held 6 months 2015: enhanced mobile broadband, large-scale machine communication, and high-reliability low-latency communication. The three application scenes respectively correspond to different key indexes, wherein the peak speed of a user in the enhanced mobile bandwidth scene is 20Gbps, and the lowest user experience rate is 100 Mbps. The unique high carrier frequency and large bandwidth characteristics of millimeter waves are the main means for realizing 5G ultrahigh data transmission rate. However, in future mobile phones, the space reserved for the 5G antenna is small, and the number of selectable positions is small, so that a miniaturized antenna module is designed.

The rich bandwidth resources of the millimeter wave frequency band provide guarantee for high-speed transmission rate, but due to severe space loss of electromagnetic waves of the frequency band, a wireless communication system utilizing the millimeter wave frequency band needs to adopt a phased array architecture. The antenna is an indispensable component in the rf front-end system, and the system integration and packaging of the antenna and the rf front-end circuit become a necessary trend for the future rf front-end development while the rf circuit is developing toward the direction of integration and miniaturization.

No matter the antenna form of the conventional millimeter wave broadband antenna based on the PCB is Patch (Patch), Dipole (Dipole), slot (slot) and the like, because the bandwidth requirement covers n257, n258 and n260, the thickness of the PCB can be increased, the number of layers at the moment is increased, and because in a millimeter frequency band, the precision requirements of multilayer PCBs on hole, line width and line distance are high, and the processing difficulty is high.
