Abstract

The invention discloses a vivaldi antenna, and relates to the technical field of antennas for communication. The vivaldi antenna comprises a first antenna unit and a second antenna unit of the same size, wherein the first antenna unit and the second antenna unit include antenna dielectric plates and radiation patches; an upper side of the middle of a dielectric layer on the first antenna unit is provided with a first slot from top to bottom; the radiation patch on the second antenna unit is symmetrically arranged on an upper surface of the dielectric layer with the first slot as an axis of symmetry; a lower side of the dielectric layer on the second antenna unit is provided with a second slot from bottom to top; the radiation patch on the second antenna unit is symmetrically arranged on the upper surface of the dielectric layer with the second slot as an axis of symmetry; and the first antenna unit and the second antenna unit are connected together in a crosswise manner. The vivaldi antenna has the advantages of high gain, high efficiency and radiation stability.

Description

technical field [0001] The invention relates to the technical field of communication antennas, in particular to a vivaldi antenna. Background technique [0002] The traditional near-field measurement is limited by the narrow frequency band of the probe antenna and only one polarization. These deficiencies make the approach measurement cumbersome and inefficient. In order to achieve fast and high-precision near-field testing, broadband dual-polarization probe antennas are being widely used in near-field measurements. In order to achieve impedance matching in a wide frequency band, chip resistors are loaded on the antenna radiation arm, which will lead to a reduction in antenna efficiency and antenna gain. Contents of the invention [0003] The technical problem to be solved by the invention is how to provide a vivaldi antenna with high gain, high efficiency and stable radiation. [0004] In order to solve the above-mentioned technical problems, the technical solution adop...
