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 had a clear solution so far, but with the rapid development of millimeter wave communication systems, the necessity and practical significance of proposing a solution for all-round coverage of terminal equipment signal radiation is self-evident Metaphor

Abstract

The invention discloses a mobile terminal millimeter wave phased array magnetic dipole antenna and a mobile terminal millimeter wave phased array magnetic dipole antenna array. The mobile terminal millimeter wave phased array magnetic dipole antenna comprises a phase-shift feed network for realizing the feed phase difference between different units and a semi-open substrate integrated waveguide resonant cavity used for realizing magnetic dipole radiation; and the semi-open substrate integrated waveguide resonant cavity adopts feed probes, and the tail end of a probe-type feed structure is connected to the phase-shift feed network. The phase-shift feed network and the semi-open substrate integrated waveguide resonant cavity are integrated onto two layers of laminated dielectric plate correspondingly, the final antenna structure is formed by the two layers of dielectric plate in a laminated mode, the lower layer is a phase-shift network layer, and the upper layer is a radiation structurelayer. The antenna array is applied to terminal millimeter wave communication so that a compact solution for solving the problem of signal coverage on the upper hemisphere surface of terminal equipment can be realized.

Description

technical field [0001] The invention relates to a mobile terminal millimeter wave phased array magnetic dipole antenna and an antenna array thereof, 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] Since the attenuation effect of the atmosphere on electromagnetic waves is re...
