Embodiment Construction

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] Such as figure 2 As shown, when using AAS to transmit a 900MHz carrier frequency signal, antenna elements 1, 2, 7, and 8 in each antenna element group are empty; image 3 As shown, when the carrier frequency signal of 1.8 GHz is transmitted, the antenna units 1, 3, 5, and 7 in each antenna unit group are vacant. However, after the antenna...

Abstract

The embodiment of the invention provides an antenna system and signal transmitting equipment. The antenna system comprises at least one antenna unit group, wherein each antenna unit group is provided with at least two antenna units in the vertical direction; each antenna unit comprises two antennae which are arranged crosswise; carrier frequency signals transmitted by at least one antenna unit group are the same; the distance between adjacent antenna units which transmit any same carrier frequency signal in each antenna unit group is the half wavelength of the frequency of the transmitted carrier frequency signal, or the difference between the distance and the half wavelength of the frequency of the transmitted carrier frequency signal is in a first setting range; and the number of the antenna units which transmit each type of carrier frequency signal is determined by the distance between adjacent antenna units which transmit the type of carrier frequency signal and the coverage radii of at least two types of carrier frequency signals transmitted by the antenna unit groups. By the embodiment of the invention, the antenna units are effectively used and prevented from being wasted or controlled, and the mounting cost and maintenance cost of the antenna system are reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an antenna system and a signal transmitting device. Background technique [0002] Advanced antenna system (Advanced antenna system; AAS) can be coordinated in full array adaptive weighting and full array static weighting, so as to realize smooth evolution and complex application of multi-antenna and network topology. AAS can perform flexible vertical beam shape and direction Adjustment, so as to perform beamforming similar to traditional horizontal beamforming in the vertical direction, enhance the signal-to-noise ratio, and improve system performance. [0003] AAS structure can be found in figure 1 As shown, it includes 4 antenna unit groups, and each antenna unit group is provided with 8 antenna units in the vertical direction, and each antenna unit includes 2 antennas. When the AAS is used to transmit different carrier frequency signals, the antenna units are usually w...
