Problems solved by technology

[0005] In the dielectric resonator antenna module in the prior art, wherein the dielectric resonator is integrated with the PCB, there are usually 2 ways to be glued (such as figure 1 shown) and SMT soldering (as figure 2 As shown), in the first method of gluing, if there is a change of a few tenths of a millimeter in the thickness of the glue, the performance of the antenna will be sharply attenuated. Connected, but the soldering tin material is uncontrollable, which will cause drastic changes in the feed impedance, thus making the antenna performance unstable. In the millimeter wave frequency band, it may cause the performance of the antenna to deteriorate, which affects the reliability of the 5G antenna, so it is necessary to A new dielectric resonator antenna module is proposed to meet the needs of 5G development

Abstract

The invention discloses a dielectric resonator antenna module and a communication terminal. The dielectric resonator antenna module comprises a dielectric resonator, a plastic clamp and a PCB. The plastic clamp is used for clamping the dielectric resonator, and the dielectric resonator penetrates through the plastic clamp; the plastic clamp is fixed on one side of the PCB; one side of the PCB is completely attached to one side of the dielectric resonator; and according to the antenna module, the clamp is introduced, and the dielectric resonator is fixed on the PCB through the clamp, so that the dielectric resonator and the PCB are completely attached; the mode is different from an existing integration mode of the dielectric resonator and the PCB, and gaps caused by uncontrollable factors such as glue or welding tin materials between the dielectric resonator and the PCB are avoided, so that impedance mismatch can be prevented and the reliability of the antenna can be improved in a millimeter wave frequency band, and meanwhile, the clamp is made of a plastic material and can also expand the bandwidth of the antenna.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a dielectric resonator antenna module and a communication terminal. Background technique [0002] 5G is the research and development focus of the global industry, and the development of 5G technology and the formulation of 5G standards have become the consensus of the industry. 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. The three application scenarios correspond to different key indicators. In the enhanced mobile broadband scenario, the peak user speed is 20Gbps, and the lowest user experience rate is 100Mbps. The unique high carrier frequency and large bandwidth characteristics of millimeter wave are the key to the realization of 5G The main means of ultra-high data trans...
