Abstract

The invention discloses a millimeter wave dielectric resonator antenna module. The millimeter wave dielectric resonator antenna module comprises a dielectric resonator and an antenna ground; the dielectric resonator is arranged on one side of the antenna ground, the dielectric resonator is located in an antenna near-field region range of the antenna ground, and an interval exists between the dielectric resonator and the antenna ground; and a feed structure is arranged at the position, corresponding to the dielectric resonator, of the antenna ground, the dielectric resonator is arranged in the antenna near-field area range of the antenna ground, a gap is formed between the dielectric resonator and the antenna ground, the antenna ground can feed the dielectric resonator through the antenna near-field area, space feed is achieved, the feed mode is simple, and the interval only needs to ensure that the dielectric resonator is within the antenna near-field region range of the antenna ground. The processing precision required by the feed mode is low, the influence of the processing error on the antenna is low, and thus the sensitivity of the antenna to the processing error of the feed structure is reduced.

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] The dielectric resonator antenna is an antenna with excellent performance, which can be used in the mobile terminal of 5G (5th-Generation, fifth-generation mobile communication technology) millimeter wave. The feeding of the current standard dielectric resonator antenna is in four forms: slot coupling feeding, microstrip feeding, CPW feeding (Cost Per Wear, coplanar waveguide) and probe feeding. These four feeding forms have high processing accuracy requirements in the millimeter wave frequency band. In addition, the processing error of the feeding structure has a significant impact on the performance of the antenna, and the relative position accuracy requirements of the feeding structure and DRA (dielectric resonator) Also very high (significant sensitivity to bit e...
