Abstract

The invention discloses a multi-arc microstrip dielectric resonant cavity antenna based on a 3D printing technology. A main radiation unit is a hemispheroid medium, and compared with a metal material,the ohmic loss is lower, and the efficiency is higher. Because photosensitive resin is used as a medium, the shape can be changed as required. The radius is slightly greater than one wavelength, andthe antenna is coupled with the current of the feed sheet, so that the radiation direction can be guided, the gain reduction caused by the dispersion of electromagnetic waves to the periphery is avoided, and the bandwidth is improved. The two layers of multi-arc micro-strips block diffusion of current to the periphery to a certain extent, and play a certain role in restraining a magnetic field, sothat backward gain is reduced, forward gain is improved, and bandwidth is further improved. And the metallized via holes are adopted, and the ground plate and the arc microstrip are connected, and therefore, current diffusion can be further suppressed, and the gain of the antenna can be improved to a certain extent.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a multi-arc microstrip dielectric cavity antenna based on 3D printing technology. Background technique [0002] With the development of communication technology, it is difficult to obtain a wide continuous bandwidth in the communication frequency band below 6GHz. Because of the large amount of unused resources, millimeter wave has become a hot spot in 5g communication research. Research on communication antennas in wave frequency band. Due to the skin effect of the metal, the traditional microstrip antenna has high metal ohmic loss and low gain in the high frequency band, which limits its development and application. Contents of the invention [0003] In view of the above problems, the present invention proposes a multi-arc microstrip dielectric resonant cavity antenna based on 3D printing technology to solve the problem of too much ohmic loss and too low efficiency of ordina...
