Problems solved by technology

[0004] However, for PCB-based conventional mmWave broadband antennas, no matter the antenna form is a patch antenna (patchantenna), a dipole antenna (dipole antenna) or a slot antenna (slot antenna), the thickness of the PCB will increase as the bandwidth to be covered increases. increase, resulting in an increase in the size of the antenna module
For antenna PCBs used in the millimeter wave band, as the number of PCB layers increases, the accuracy requirements for holes, line widths, and line spacings of multilayer PCBs will increase, resulting in increased processing difficulty and difficult to realize millimeter wave antenna modules. Simultaneous coverage of multiple frequency bands

Abstract

The invention discloses a millimeter wave dielectric resonator antenna module and communication equipment. The antenna module comprises a dielectric resonator module, a dielectric layer and a metal ground; the dielectric resonator module is of a ceramic body structure and is located on one side of the dielectric layer. The metal ground is positioned on one side, far away from the dielectric resonator module, of the dielectric layer; the metal ground is provided with a grid structure corresponding to the dielectric resonator module, the dielectric resonator module is made of a ceramic body structure, and the metal ground is provided with the grid structure corresponding to the dielectric resonator module, so a feed form can be changed to excite various dielectric resonator antenna modes, and the TEnmp modes and the TMnmp modes can be excited at the same time; moreover, the resonance generated by the modes is generally adjacent, and a broadband can be formed, so the antenna module can cover n257, n258 and n261 frequency bands, an ultra-wideband antenna is finally formed, and the frequency band coverage rate of the antenna module is increased.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a millimeter-wave dielectric resonator antenna module and communication equipment. Background technique [0002] 5G (5th-Generation, fifth-generation mobile communication technology) 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. Among them, the peak user speed in the enhanced mobile bandwidth scenario is 20Gbps, and the minimum user experience rate is 100Mbps. [0003] Since the millimeter wave has high carrier frequency and large bandwidth char...
