Embodiment Construction

[0025] In order to make those skilled in the art more clearly understand the purpose, technical solutions and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Such as figure 1 As shown, in one embodiment of the present invention, the broadband dual-polarized rhombic dipole unit includes four dipoles 10 that are center-symmetrical and orthogonally combined to form a polarization distribution of plus or minus 45 degrees. Each dipole 10 It includes two dipole arms 11 coupled to each other and a feed balun 20 connected to the feed end 12 of the dipole arm 11. The dipole arm 11 gradually widens from the feed end 12 to the end 13 to form a polygonal shape, wherein , the feed balun 20 is used as a supporting structure for supporting and fixing the dipole arm 11 .

[0027] Such as figure 2 As shown, the four dipoles 10 are distributed on the same plane, the opposite dip...

Abstract

The invention discloses a broadband dual-polarized rhombic oscillator unit and a linear array antenna. The broadband dual-polarized rhombic oscillator unit comprises four dipoles which are in centralsymmetry and are orthogonally combined to form positive and negative 45-degree polarization distribution, wherein each dipole comprises two oscillator arms which are coupled with each other and a feedbalun connected with the feed ends of the oscillator arms, and the oscillator arms are gradually widened from the feed end to the tail end to form a polygonal shape. The broadband dual-polarized rhombic oscillator unit comprises four dipoles which are in central symmetry and are orthogonally combined to form positive and negative 45-degree polarization distribution, and the oscillator arms of thedipoles are gradually widened from the feed end to the tail end to form a polygonal shape, so that the widths of the oscillator arms are increased, the impedance bandwidth is increased, the relativebandwidth of the dipoles reaches 35%, the problem of narrow impedance bandwidth of a conventional dual-polarized rhombic oscillator antenna is solved, and the broadband purpose is achieved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a broadband dual-polarization rhombic dipole unit and a linear array antenna. Background technique [0002] Mobile communication has played an important supporting role for information communication in today's society.
