In this embodiment, the substrate 10 of the dielectric resonator antenna 100 is a bottom copper-clad printed board, such as a PCB board, and the ground board on the first surface 101 is used for grounding the dielectric resonator antenna 100, and in an alternative embodiment, the ground board completely covers the first surface 101. The dielectric resonance unit 20 is a multi-layer dielectric cylinder, and the probe 30 is a coaxial probe, i.e. the central axis of the probe 30 is the same as the central axis of the multi-layer dielectric cylinder. The dielectric resonance unit 20 is divided into an upper section, a middle section and a lower section, and the diameters of the three sections are different from each other.
The dielectric resonance unit 20 includes a first dielectric pillar 201, a second dielectric pillar 202, and a third dielectric pillar 203 stacked on the substrate 10 in this order, and the probe 30 abuts inside the first dielectric pillar 302 of the dielectric resonance unit 20 through a probe hole. The probe hole is a hole opened at the inner center of the first dielectric pillar 201 for matching with the probe 30, and is not marked in the drawing.

The bulge 301 is used for impedance matching, so that impedance change of each frequency band is small, good impedance matching is achieved, and the frequency combination can enable the whole dielectric resonator antenna to have a wide working bandwidth. The substrate 10 is, for example, a circular structure, and a through hole is formed in the center for the probe 30 to pass through. Further, the substrate 10, the parasitic metal ring 40, the annular patch 50, the dielectric resonance unit 20, the protrusion 301, and the probe 30 are coaxially disposed, and the probe 30 sequentially passes through the centers of the substrate 10, the annular patch 50, the first receiving groove 2011, the protrusion 301, and the first dielectric column 201.

The utility model discloses the people selects above-mentioned dielectric resonator antenna that the embodiment of this invention provided to carry out performance test, and figure 6 to figure 8 show the E face directional diagram of antenna at three different frequency point department of 2GHz, 3GHz and 4GHz in proper order. Also, in fig. 6 to 8, the closed curves indicated by the solid lines represent cross-polarization curves. From the results in fig. 5, it can be seen that the antenna has a wide impedance matching impedance bandwidth, and the return loss of the antenna in the whole frequency band (for example, from 2.02Hz to 3.99Hz) is less than-10 dB, which meets the engineering use requirement. As can be seen from the results in fig. 6 to 8, the gain of the operating band antenna is up to 2.51dBi, the gain fluctuation of the antenna azimuth pattern is less than 0.3dB, the antenna has excellent omnidirectional radiation characteristics in the whole operating band, and the cross polarization level is low.
Therefore, in the dielectric resonator antenna of the embodiment of the utility model, under the condition of the size layout of the traditional DRA antenna, the traditional single-mode radiation dielectric resonator antenna is changed into a broadband dielectric resonator mode, a coaxial probe resonator mode and an annular microstrip patch resonator mode. Meanwhile, the resonant frequency ranges of all modes of the antenna are close by adjusting all parameters, so that broadband work is realized. The dielectric resonant antenna has the characteristics of broadband and high gain under the condition of small size, saves the installation space, and can be conformal with a carrier platform when used for ground communication and aircraft communication.

In the theoretical design of the traditional dielectric resonant antenna, the working bandwidth of the antenna is improved mainly by changing the shape of a medium and increasing the number of layers of the medium, but the improvement of the working bandwidth cannot meet the requirements of certain special scenes. However, the dielectric resonant antenna of the embodiment of the utility model utilizes the coaxial probe to excite the multilayer dielectric cylinder to realize the omnidirectional vertical polarized wave radiation of two resonant modes; meanwhile, the addition of the parasitic metal ring introduces an ideal conductor boundary condition, so that the electric field distribution in the medium is changed, and the resonance working bandwidth of the antenna is expanded; finally, an annular microstrip patch is printed on the upper layer of the bottom printed board, so that a new radiation mode is excited, the antenna can work in a frequency band which is wide enough (about 67%), and the antenna is greatly improved compared with a traditional DRA antenna.
