Problems solved by technology

However, the use of a single antenna or a single antenna array cannot meet the requirements of omni-directional hemispherical coverage of the signal of the handheld terminal device in the entire three-dimensional space.
For this practical problem, the industry has not yet had a clear solution so far, but with the rapid development of 5G millimeter wave communication systems, the necessity and practical significance of proposing a solution for all-round signal radiation coverage of terminal equipment goes without saying and metaphor

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] like figure 1 and 2 As shown, the present invention is a millimeter-wave end-fire dual-polarized antenna, which includes a magnetic dipole antenna unit based on a semi-open substrate-integrated waveguide resonator and a substrate-integrated waveguide as an electrical feed balun. The dipole antenna unit, the semi-open substrate-integrated waveguide resonator is integrated on the first dielectric plate 9, the substrate-integrated waveguide is integrated on the second dielectric plate 10 as the electric dipole radiation of the feeding balun, and the first dielectric plate 9 is an upper dielectric board, and the second dielectric board 10 is a lower dielectric board. The antenna structure of the present invention is formed by laminating two dielectric boards.

[0033] When this antenna is applied to the millimeter wave communication of the terminal equipment, it i...

Abstract

The invention discloses a millimeter-wave dual-polarized antenna for a mobile terminal. The millimeter-wave dual-polarized antenna consists of a magnetic dipole antenna unit based on a semi-open substrate integrated waveguide resonator and an electric dipole antenna unit taking substrate integrated waveguide as a feeding balun. According to the millimeter-wave dual-polarized antenna, three antennas are respectively mounted on the left side, the right side and the upper side of equipment, so that a three-dimensional space signal cover demand of terminal equipment exceeding a hemisphere can be met; and the characteristic of dual polarization can be provided.

Description

technical field [0001] The invention relates to a millimeter-wave dual-polarized antenna for a mobile terminal, belonging to the technical field of wireless communication. Background technique [0002] As one of the important components of the wireless communication system, the performance of the millimeter-wave antenna or antenna array directly determines the performance level that the system can achieve. For terminal equipment, it is even more required that the antenna used not only meet the traditional bandwidth and gain indicators, but also have the characteristics of miniaturization and wide beam coverage; in particular, if the antenna can also have end-fire radiation characteristics, then It can bring more additional benefits such as improving energy utilization and reducing interference between the antenna and the internal circuit of the device. [0003] Due to its advantages in resisting channel interference, dual-polarization (two mutually orthogonal linear polariz...
