A dual-polarized broadband antenna dipole unit and a broadband dual-polarized antenna

Abstract

The present invention is applicable to the technical field of communication, and provides a dual-polarized broadband antenna vibrator unit including: a radiator and a balanced feeding device; the radiator includes four radiating arms, and each radiating arm is provided with a hollow structure; each The periphery of the radiating arms is polygonal and includes a notch part matching the shape of the peripheral conductor, and the notch part of each radiating arm is electrically connected to a part of the corresponding peripheral conductor; each radiating arm is The corners opposite to the missing corners are provided with an open circuit, which is hollowed out together with the hollow structure, and the open circuit divides the opposite corners of the missing corners into two mutually symmetrical ends; a loading section is respectively extended from the two mutually symmetrical ends, The adjacent radiation arms form a closed electromagnetic loop through the electromagnetic coupling between the loading sections of the adjacent radiation arms. The invention is simple in structure, easy to manufacture, and has the advantages of beam convergence, excellent radiation performance and wide frequency band, and can realize the optimization of the electric performance of the antenna.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a dual-polarization broadband antenna vibrator unit and a broadband dual-polarization antenna. Background technique [0002] With the rapid development of mobile communication, the working frequency bands of various systems are also expanding. The working frequency of the smart antenna in the TD-SCDMA network is 1880-1920MHz, 2010-2025MHz, 2300-2400MHz; the communication frequency of DCS is 1710- 1880MHz; the communication frequency of PCS is 1850-1990MHz; the communication frequency of UMTS is 1920-2170MHz; part of the communication frequency band for global microwave interconnection access is 2300-2690MHz. Therefore, a market demand for a broadband antenna with a working frequency range of 1710-2690 MHz that can take into account the above standards has been proposed. However, the relative frequency bandwidth of 1710-2690MHz reaches 44.5%, which is generally ...
