Abstract

The embodiment of the invention provides a millimeter wave antenna array with a characteristic of diversified oblique transmission angles. The antenna comprises substrate integrated waveguide ports, feed network units and antenna units, wherein the substrate integrated waveguide ports are used for receiving signals and feeding the received signals into a feed network layer; the feed network unitsare used for being mutually stacked through the dual-polarized two-layer feed network layer, carrying out coupled feeding upward through planar slots, determining the phase difference of the signals,acquiring signals to be transmitted and transmitting the signals to be transmitted to the antenna units, and signals with different phase differences are different in transmission angle; and the antenna units are used for receiving the to-be-transmitted signals transmitted by the feed network units and transmitting the to-be-transmitted signals outward in the form of millimeter waves. The millimeter wave antenna array with the characteristic of diversified oblique transmission angles has the characteristics of broadband, high gain and diversified oblique transmission angles, realizes the oblique transmission characteristic of the millimeter wave antenna array, and ensures the characteristics of broadband and high gain of the antenna.

Description

technical field [0001] The present application relates to the technical field of antennas for wireless communication terminals, in particular to a millimeter-wave antenna array with diverse oblique angle characteristics. Background technique [0002] As a transformer, the antenna transforms the guided wave propagating on the transmission line into a wave propagating in an unbounded medium (usually free space), or vice versa, and is used in radio equipment to transmit or receive waves. Antennas are widely used in engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy. Those who use waves to transmit information rely on antennas to work. With the improvement of communication technology, extensive achievements have been made in the field of antenna technology, such as 3G (3rd-Generation, third-generation mobile communication technology) smart antenna, 3G directional and omnidi...
