Problems solved by technology

However, there are very few reports in the literature on the application of high-order modes to generate high-gain radiation.
In 2009, an article entitled "Higher-Order Modes in Rectangular DRAs for Gain Enhancement" published by Aldo Petosa and Soulideth Thirakoune proposed the use of DRA's high-order mode mode to achieve an effective increase in antenna gain, but the disadvantage is that it works in high-order modes mode antenna has too high profile, which limits its application in practical engineering

Abstract

The invention discloses a high-gain rectangular dielectric resonator antenna working in a high-order mode, and belongs to the technical field of electronics. The antenna comprises a rectangular medium substrate, a microstrip line arranged on the lower surface of the medium substrate, a metal earth plate arranged on the upper surface of the medium substrate and etched with a rectangular seam, and a rectangular medium block arranged at the center of the upper layer of the earth plate. The antenna is coupled to a DRA through the caliber of the rectangular seam so that the required high-order mode can be excited, the mode has the advantage of being higher in orientation compared with a basic mode, and therefore the higher radiation gain can be obtained; in addition, the antenna has the advantages of being simple in structure, capable of conveniently conducting feed, compact in structure and the like, and has high practical application value.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a rectangular dielectric resonator antenna technology for obtaining high gain by working in a high-order mode. Background technique [0002] In today's environment of rapid development of the wireless communication industry, due to the increasing integration of electronic components in engineering, higher and higher requirements are put forward for the size, frequency bandwidth, loss and gain of the antenna. How to effectively meet the above requirements has become a The direction that many scholars focus on. Since the dielectric resonator antenna (DRA) was proposed in 1983, it has been extensively studied due to its advantages in diverse forms, small size, low loss, flexible excitation, low cost, and high radiation efficiency. Typical dielectric resonator antennas have rectangular, cylindrical, and hemispherical shapes, among which rectangular DRA has received m...
