Problems solved by technology

However, the general dual-polarized millimeter-wave dielectric resonator antenna has the following problems: the standard dielectric resonator is a discrete cuboid, cylinder, sphere and other shapes, when the multi-unit dielectric resonator array antenna and PCB (Printed Circuit Board, Circuit board) will produce alignment error during assembly, resulting in antenna impedance mismatch and radiation performance degradation
For example, a 1X4 cuboid dielectric resonator antenna array needs to be installed on the PCB board 4 times, then the NXN unit will introduce N 2 Sub-artificial errors, in the millimeter wave frequency band, the impedance mismatch of multiple units will cause the overall radiation performance of the antenna to deteriorate

Description

technical field [0001] The invention relates to the technical field of 5G antennas, in particular to a dual-polarization integrated dielectric resonator millimeter wave module and a communication terminal. Background technique [0002] As 5G is the research and development focus of the global industry, it has become an industry consensus to develop 5G technology and formulate 5G standards. At the 22nd meeting of ITU-RWP5D held in June 2015, the International Telecommunication Union ITU clarified three main application scenarios of 5G: enhanced mobile broadband, large-scale machine communication, and high-reliability and low-latency communication. These three application scenarios correspond to different key indicators. In the enhanced mobile bandwidth scenario, the user peak speed is 20Gbps, and the minimum user experience speed is 100Mbps. The unique high carrier frequency and large bandwidth characteristics of millimeter wave are the main means to achieve 5G ultra-high da...
