Antenna oscillator, antenna unit and antenna

Abstract

The embodiment of the invention provides an antenna oscillator, an antenna unit and an antenna, belonging to the technical field of communication. The antenna oscillator comprises two pairs of oscillators; each pair of oscillators comprises two frame oscillators; each frame oscillator is provided with an opening and internally provided with a linear oscillator; one end of the linear oscillator isopposite to the opening of the frame oscillator and keeps a certain distance; the other end of the linear oscillator is electrically connected with a body at the opposite end of the opening of the frame oscillator; the two frame oscillators of each pair of oscillators are fixedly connected through the electrically connected linear oscillators in each frame oscillator; and the two oscillators are mutually connected through parts for fixing linear oscillators in the frame oscillators in each pair of oscillators. The antenna oscillator can reduce the plane beam width of the oscillators so that the antenna unit made by utilizing the antenna oscillator can form the needed beam width by only matching with a smaller reflection plate, and the made antenna is minimized.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an antenna dipole, an antenna unit and an antenna. Background technique [0002] The antenna is an energy conversion device in the mobile communication system. It is generally used in conjunction with the base station. The electromagnetic wave signal emitted by the mobile station of the base station is converted into an electrical signal by the antenna for processing by the base station; conversely, the base station converts the electrical signal into an electromagnetic signal through the antenna. The signal propagates in the free space, and the mobile station can receive it randomly, so as to realize the two-way communication of the communication system. With the development of the operator's network, more and more antennas need to be installed at the same site. A large number of antennas need to be installed on a steel tower or pole. If the antenna is large, it will take ...

AI Technical Summary

Problems solved by technology

[0005] From the above introduction to the existing antenna unit, it is found that the existing technology has at least the following problems: Since the input impedance of the half-wave oscillator of the antenna unit itself is 75 ohms, and the output impedance is 50 ohms, it is necessary to increase impedance matching on the balun part, and an impedance matching section is a quarter wavelength, so it also determines that the height of the half-wave dipole antenna must meet a quarter wavelength to achieve impedance matching

In turn, the thickness of the antenna is still very thick. In addition, due to the current concentration on the vibrator, the induced current can only be excited in a small area of ​​the reflector, resulting in a wider beam width. In order to achieve the required beam width, only through Increase the reflector width to achieve

Therefore, due to these two reasons, the thickness of the existing half-wave dipole antenna unit is relatively high, and the width of the reflecting plate matched with it is relatively wide, resulting in a large volume of the antenna
