Oriented linear polarization is convenient. According to a bipolar dipole antenna disclosed in US Pat. No. 6,819,300 B2, the single-dipole 13 and its dipole half 13 (15, ')' are each independently arranged, so the single-dipole and The distance between the dipole halves and the height and the low position are not easy to maintain, and the feeding mode of the dual-polarized pole antenna is used for the feed line 27 by the rod-shaped elbow 35 extended by the dipole and its dipole half. Electrically connected, the elbow milk is not easy to electrically connect the feeder 27 and position the inner and outer conductors. In addition, for a dual-polarized antenna for a base station, since each antenna device to 4 includes radiation ridges of two polarization units, the antenna should operate in two different frequency ranges (for example, CDMA 800 MHz). In the frequency band and the GSM 900MHz band), when the radiators of the two polarization units simultaneously transmit and receive two 3 M375302 'frequency ranges of RF signals, if the isolation of the operating frequency is not good, it will cause mutual interference and reduce the antenna. Gain and efficiency, which in turn affects the quality of communication, if complicated and precise electronic components are added to increase the isolation of two operating frequencies, it will cause the base station's dual-polarized antenna to be difficult to manufacture, assemble and costly. [New content] In view of the problems caused by the above prior art, the main purpose of the present invention is to provide a dual polarization that can improve the separation of the operating frequency of the dual-polarized antenna to reduce interference and improve communication quality. Antenna structure. Another object of the present invention is to provide a dual-polarized antenna structure that improves the stability of the radiator positioning and the ease of feeding. According to the purpose of the present invention, a dual-polarized antenna structure is proposed. The antenna is as follows: The antenna comprises: at least four radiators and fixed to the reflector by means of a balancing device and a base, wherein the radiator has Special-specific feeding structure to improve the stability of the radiator positioning and the ease of feeding. The reflector is provided with a gap to improve the isolation of the operating frequency signal of the dual-polarized antenna to reduce interference and improve the quality of communication. By. In order to clarify the purpose, features, and advantages of the present invention, a preferred embodiment will be described below in detail with reference to the accompanying drawings. FIG. 1 and FIG. A schematic diagram of a dual-polarized antenna structure according to a preferred embodiment of the present invention is shown. The antenna 1 comprises: at least four radiators 10 and is fixed relative to the reflector 40 by means of the balancing device 20 and the base 30. 4 M375302 'The four radiators 10 are arranged in an orthogonally symmetric manner in the ±45° direction. Each radiator 10 comprises: a balancing device 20, at least two radiating arms 11, 12, a feed structure 50, The balance device 20 is composed of two spaced apart support arms 21, 22, the bottom end of which is connected with the base 20, and the support arms 21, 22 extend obliquely from the bottom end to the top end and respectively respectively. The arms 11, 12 are connected such that the two radiating arms 11, 12 each extend in the opposite direction by an appropriate length, and the radiating arms 11, 12 of the adjacent radiators 10 have appropriate gaps 13, each of which is oppositely disposed. The set of radiators 10 constitutes a first, two polarization-directed radiating element assembly for transmitting and receiving RF signals of two frequency ranges. The four radiators 10, together with the balancing device 20, can be fixed to the reflecting plate 40 by means of a base 30 with screws or welding. The four radiators 10 together with the balancing device 20 and the base 30 can be integrally formed.
