Problems solved by technology

[0003] According to 3GPP TS38.101-2 5G terminal radio frequency technical specification and TR38.817 terminal radio frequency technical report, 5GmmWave frequency bands include N257 (26.5-29.5GHz), N258 (24.25-27.25GHz), N260 (37-40GHz), N261 (27.5-28.35GHz) and the newly added N259 (39.5-43GHz), which span a large frequency band, traditional antennas cannot meet the communication needs in 5G scenarios, and broadband antennas or dual-band antennas need to be designed to cover these frequency bands
[0004] The conventional millimeter-wave broadband antenna based on PCB, including the antenna form is PATCH (patch antenna), dipole (dipole antenna), SLOT (slot antenna), etc., in the case of bandwidth requirements covering N257, N258 and N260, It will increase the thickness of the PCB. At this time, the number of layers also needs to be more adaptable, and because in the millimeter frequency band, multi-layer PCBs have high requirements for the accuracy of holes, line widths, and line spacing, and the processing is difficult.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an ultra-wideband dielectric resonator antenna and communication equipment. 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 data transmission rate. [0003] ...
