Embodiment Construction

[0031] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings and the technical solutions of the description.

[0032] see figure 1 A perspective view of the overall structure of a low-profile, high-gain antenna. The antenna as a whole is composed of a high-permittivity dielectric block 1 on the top layer, a low-permittivity dielectric substrate 2 on the middle layer, and a low-permittivity dielectric substrate 6 on the bottom layer.

[0033]See Figure 2(a) The dielectric structure with high dielectric constant on the top layer is composed of eight identical rectangular parallelepiped dielectric blocks 1, arranged vertically in a column of four, with a small air gap 10A between the four rectangular parallelepiped dielectric blocks in each column Separated, the two rows of dielectric structures formed are placed in parallel horizontally at a fixed interval 10B, and finally constitute the overall dielectr...

Abstract

A low-profile and high-gain broadband dielectric resonator antenna belongs to the technical field of wireless communication and antennas, and comprises a three-layer structure, wherein the top layer is a dielectric layer with a high dielectric constant, the middle layer is a middle layer dielectric substrate with a low dielectric constant, and the bottom layer is a bottom layer dielectric substrate with a low dielectric constant. A plurality of separated dielectric blocks with high dielectric constants are longitudinally arranged to excite a plurality of modes of the dielectric resonator antenna, two groups of separation modules are transversely arranged to form an array form at a low frequency to increase gain, and the two groups of separation modules are regarded as a whole at a high frequency to excite a high-order mode of the dielectric resonator antenna, so the high-gain radiation is realized while the bandwidth is further broadened. According to the broadband dielectric resonatorantenna, the problem that the profile height of an existing broadband dielectric resonator antenna is high is solved, and on the basis of a low profile, the broadband coverage performance is achieved. The antenna has the characteristics of high efficiency, light weight and low processing cost, and is beneficial to market promotion.

Description

technical field [0001] The invention belongs to the field of wireless communication and antenna technology, and relates to a low-profile and high-gain broadband dielectric resonator antenna. Background technique [0002] The Sub-6G frequency band has become a key frequency band for the development of the fifth generation mobile communication technology (5G) due to its advantages in transmission distance and cellular coverage, and the research and development of related technologies has also become the cornerstone of 5G construction. At the same time, the Sub-6G frequency band can still use the relevant frequency bands and technologies developed in the 4G era, saving operators' network construction costs, and can take into account both network coverage and building internal penetration capabilities. Most of the frequencies used in 4G communications are lower than 2.6GHz. The newly added mid-frequency bands in the sub-6G frequency band for 5G construction are higher than the f...
