Abstract

The invention discloses a millimeter wave antenna, and belongs to the technical field of antennas. The millimeter wave antenna comprises an N-layer dielectric substrate, a first metal layer, a secondmetal layer, a first radiation patch, a feed structure and a plurality of conductive structures, wherein the first metal layer, the N-layer dielectric substrate and the second metal layer are stacked.A plurality of conductive structures penetrate through the N-layer dielectric substrate. Each conductive structure is connected with the first metal layer and the second metal layer, and a pluralityof conductive structures can form a dielectric cavity through enclosing. The feed structure is used for feeding an excitation signal to excite the dielectric cavity to resonate at a first resonance frequency. According to the millimeter wave antenna, the dielectric cavity can be excited by the excitation signal fed by the feed structure to generate the millimeter wave signal of the first resonantfrequency in the mode of a higher-order mode so as to ensure the effectiveness of high gain of the millimeter wave antenna and reduce the space occupied by the millimeter wave antenna in the terminal.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to a millimeter-wave antenna and electronic equipment. Background technique [0002] With the advent of the fifth generation of mobile communication (5G), millimeter wave antenna technology has received more and more attention as one of its core technologies, and it will inevitably be applied to various terminals (such as mobile phones, tablet computers, mobile wearable devices) in the future. Wait). Wherein, the millimeter wave antenna refers to an antenna whose working frequency is in the range of 24.25 GHz-52.6 GHz. [0003] During the use of millimeter-wave antennas, multiple millimeter-wave antennas are usually arranged in an array to increase the bandwidth of the millimeter-wave antenna. However, this arrangement of millimeter-wave antennas not only increases the overall Design difficulty also increases the volume occupied by the entire millimeter-wave antenna. ...
