Abstract

The invention discloses an orthogonal elliptical-table-shaped dielectric resonator antenna for a 5G millimeter wave band. A main radiation unit is an orthogonal elliptical-table-shaped dielectric, andcompared with a metal material, the orthogonal elliptical-table-shaped dielectric resonator antenna is lower in ohmic loss, higher in efficiency, simple in structure and low in processing cost. The grooves on the dielectric surface can reduce the loss and improve the antenna gain. The orthogonal elliptical gap can be better attached to the orthogonal elliptical-table-shaped medium, and the coupling efficiency is higher. Simulation comparison shows that the gain of the orthogonal elliptical gap is higher than that of a common gap. Stripline feed can reduce backward radiation and improve the gain. Two circles of through holes are formed in the stripline, so that energy can be concentrated at the dielectric radiation unit, and the gain is further improved. Compared with the prior art, the antenna can obtain higher gain in a 5G millimeter wave band, the highest gain reaches 13.52 dB, and the bandwidth reaches 3.95 GHz.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an orthogonal elliptical table-shaped dielectric resonator antenna for 5G millimeter wave band. Background technique [0002] With the rapid development of the wireless communication industry, higher requirements are put forward for the miniaturization, broadband, and low loss of the antenna. Although various microstrip antennas have been deeply researched and Widely used, but due to the advent of the 5G era, the application of antennas must move towards higher frequency bands. In high frequency bands, metal ohmic losses are high and processing is difficult, so its development and application are limited. Contents of the invention [0003] In view of the above problems, the present invention proposes an orthogonal elliptical table-shaped dielectric resonator antenna for the 5G millimeter wave band to solve the problem of excessive ohmic loss of the antenna in the high frequenc...
