Embodiment Construction

[0027] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0028] The millimeter-wave antenna provided in this application may be, but not limited to, a millimeter-wave millimeter-wave antenna applied to 5G communication.

[0029] Millimeter wave antennas have the advantage of thin thickness, but also have the disadvantage of narrow bandwidth. While designing a thin, small and easy-to-process millimeter-wave antenna, it is an important and difficult point in the design of millimeter-wave antennas to take into account the performance of antenna bandwidth and gain.

[0030] In one embodiment, such as Figure 1 to Figure 4 As shown...

Abstract

The application relates to a millimeter wave antenna, comprising a ground layer, a first dielectric layer, a feed layer, a second dielectric layer, a first radiation layer, a third dielectric layer and a second radiation layer, which are arranged orderly layer by layer, wherein the feed layer is configured to receive a feed and transmit the received feed energy to the first radiation layer in a coupled manner; the first radiation layer is configured to receive the feed energy transmitted by the feed layer, radiate a portion of the feed energy received to generate a first resonant peak and alsotransmit the other portion of the feed energy received to the second radiation layer in a coupled manner; and the second radiation layer is configured to receive the feed energy transmitted by the first radiation layer and radiate the feed energy received to generate a second resonant peak, wherein the difference between a wavelength corresponding to the first resonance peak and a wavelength corresponding to the second resonance peak is within a preset range. The application can superimpose the radiation resonance of the first radiation layer and the radiation resonance of the second radiation layer, thereby effectively expanding the bandwidth of the millimeter wave antenna.

Description

technical field [0001] The present application relates to the technical field of communications, in particular to a millimeter wave antenna. Background technique [0002] As a signal receiving and transmitting device, the antenna has various forms, and various antenna forms have their application frequency bands and occasions. With the development of communication technology, millimeter wave communication has become the current mainstream, and millimeter wave antenna is indispensable as a receiving and transmitting device for communication system signals. [0003] In applications such as 5G mobile communication systems, new requirements are put forward for millimeter-wave antennas, that is, wider bandwidth, lower power transmission loss, miniaturized structure, and good radiation indicators. However, traditional millimeter-wave antennas have a narrow working bandwidth and poor gain performance. Therefore, how to design a thin structure while taking into account performance ...
