Embodiment 1

[0031] Embodiment 1, this embodiment proposes a structural design of a millimeter wave antenna, see Figure 1-Figure 4 As shown, the millimeter wave antenna in this embodiment is a spherical antenna structure, including radiators, first conductive pillars 11 and second conductive pillars 12 and other main components. Wherein, the radiator is designed in the shape of a hollow sphere with a gap 20; the first conductive post 11 and the second conductive post 12 are connected to the radiator, and are at least partially located in the spherical cavity formed by the radiator to form a cavity Bulk resonance probes. As a preferred embodiment, in this embodiment, a plurality of radiators 21-23 are combined to form the hollow sphere. Specifically, each of the radiators 21 - 23 may be designed in a curved surface shape, and after these radiators 21 - 23 in the curved surface shape are put together, a hollow sphere with a gap 20 can just be formed. In some embodiments, the radiators 21-...

Abstract

The invention discloses a millimeter wave antenna and wireless equipment. A radiator, a first conductive column and a second conductive column are included. The radiator forms a hollow sphere with a notch. The first conductive column is connected with the radiator, and one end extends into the hollow sphere to form a free end. The second conductive column is connected with the radiator, one end extends into the hollow sphere to form the free end, and the free end of the first conductive column and the free end of the second conductive column directly face each other and form a gap. The millimeter wave antenna is designed to adopt a spherical structure, and miniaturization of a size of the antenna can be achieved. The antenna can generate directional radiation towards a notch direction through a spherical cavity so that the antenna has directional high-gain performance. Through changing the notch direction of the antenna, a radiation angle of the antenna can be adjusted, and traceability of a radiation pattern of the antenna is realized.

Description

technical field [0001] The invention belongs to the technical field of wireless equipment, and relates to an antenna device in a wireless equipment, in particular to a structural design of a millimeter-wave antenna. Background technique [0002] Antenna is an important part of wireless devices used to receive or transmit electromagnetic waves. Wireless devices that transmit and receive wireless signals through antennas for communication can get rid of the shackles of signal cables and realize more abundant applications. In real life, antennas are used more and more widely, and antennas are needed in more and more electronic products. With the upgrading of wireless devices, the design of antennas also faces more challenges. [0003] In the field of wireless communication, the era of millimeter waves has come quietly. Millimeter wave (millimeter wave) is an electromagnetic wave with a wavelength of 1 to 10 millimeters. It is located in the wavelength range where microwaves an...
