Abstract

The invention discloses a millimeter wave passive multi-beam array device for a mobile terminal and an implementation method of the millimeter wave passive multi-beam array device; the device is provided with a dipole antenna array with double-sided printing, a feed network formed by a dielectric substrate integrated waveguide, a passive beam forming network and a micro-strip feed network. The millimeter wave passive multi-beam array can also be formed, and the characteristics of low profile, easiness in integration and H-surface wide beam coverage can be achieved; an antenna array is fed through the phase shift characteristics of the different input ports of the passive beam forming network, so that the beam scanning characteristic of the E surface and the multi-beam characteristic can beobtained; and by adoption of the scheme of the three pairs of electric dipole antenna arrays, the three-dimensional space coverage requirement of the terminal equipment over the hemisphere can be met, wherein the main space region meets the double polarization requirement.

Description

technical field [0001] The invention belongs to wireless communication technology, and in particular relates to a millimeter-wave passive multi-beam array device for a mobile terminal and an implementation method thereof. Background technique [0002] In the future wireless communication system, the millimeter wave frequency band has a vast undeveloped spectrum, which can provide support for further increasing the communication rate. Therefore, the millimeter-wave frequency band has received extensive attention from various countries and has become a research focus worldwide. At present, more and more countries and regions have begun to adopt the millimeter-wave frequency band as a candidate frequency band for the fifth-generation mobile communication system. The millimeter-wave frequency band has a lower wavelength, which can make the device miniaturized and facilitate system integration. However, due to the attenuation effect of the atmosphere on electromagnetic waves in ...
