Abstract

The invention provides a four-mode broadband high-gain differential dielectric resonator antenna. The antenna comprises a radiation unit comprising at least one cuboid dielectric resonator, two T-shaped excitation structures being arranged in parallel on a pair of opposite side surfaces of each dielectric resonator; a metal ground; and a metal circuit layer, provided with an input port; wherein the T-shaped excitation structure comprises a transverse metal strip and a vertical metal strip, one end of the vertical metal strip is connected with the middle part of the transverse metal strip, andthe other end of the vertical metal strip is connected with the first dielectric plate. According to the four-mode broadband high-gain differential dielectric resonator antenna provided by the invention, the gain of 4-5dBi is improved compared with the prior art through the sum of four higher modes of the dielectric resonator and the design of the differential dielectric resonator antenna, but thedesign complexity of a feed network is greatly reduced, and a wider radiation bandwidth is obtained.

Description

technical field [0001] The invention relates to the technical field of dielectric resonant antennas, in particular to a four-mode broadband high-gain differential dielectric resonator antenna. Background technique [0002] With the continuous development of modern wireless communication, the communication system has higher and higher requirements on the RF front-end antenna. Differential antennas have become a major research hotspot at home and abroad because of their advantages such as stable and symmetrical pattern and high integration, and have gradually been introduced into wireless communication systems. In recent years, differential antennas have been extensively studied. Among them, the dielectric resonator has many advantages such as high no-load quality factor, good temperature stability, flexible design, various feeding methods, and simple manufacturing process, and has become an important choice for differential antennas. The radiation passband of the existing d...
