Problems solved by technology

[0004] Sometimes, in order to obtain higher gain of the antenna or make the antenna smaller in size, it is necessary to reduce the distance between the vibrator and the reflector. At this time, since the length of the balanced short circuit is about 1 / 4 wavelength, the vibrator of the above patent There will be limitations, and it cannot effectively increase the gain of the antenna or reduce the size of the antenna

Abstract

The invention aims at providing a wideband dual-polarization radiating unit, comprising four symmetrical vibrators, and balance short circuiting devices corresponding to the vibrators, wherein the vibrators are used for transmitting or receiving communication signals; the balance short circuiting devices are used for carrying out balance feeding for each vibrator; the vibrators and the balance short circuiting devices are respectively arranged on the same plane; and since the vibrators and the balance short circuiting devices are respectively arranged on the same plane, the supporting action of the balance short circuiting devices on the vibrators is eliminated, so that the distance from the vibrators to a reflecting plate can be adjusted randomly. In addition, the balance short circuiting devices and the vibrators are arranged in the same plane and can be manufactured by using printed boards or metal plates, the processing is convenient and the consistency is good.

Description

technical field [0001] The invention relates to the field of mobile communication antennas, in particular to a broadband dual-polarization radiation unit. Background technique [0002] The radiation unit is a key component of the base station antenna, and the antenna realizes the conversion between the energy on the transmission line and the space electromagnetic wave energy through the radiation unit. There are many forms of radiation elements, commonly used are microstrip patch radiation elements and symmetrical oscillator radiation elements, among which symmetrical oscillator type radiation elements are widely used due to their better bandwidth and cross-polarization performance. [0003] Generally speaking, a symmetrical vibrator has a balanced short circuit, also called a balun, whose function is to make the currents on the two radiation arms of the symmetrical vibrator the same size, thereby improving the radiation characteristics; the length of the balanced short cir...
