Description

Antenna and communication equipment The present application is a divisional application, the original application number is 202111540850.7, the application date is 2021, 12, 16, the entire contents of which are incorporated herein by reference. Technical Field The present application relates to the field of communications technologies, and in particular, to an antenna and a communications device. Background With the development of wireless communication technology, the base station can support more and more communication frequency bands, and the antennas installed on the holding pole are more and more. Because the locations on the poles for mounting the antennas are limited, some poles cannot accommodate more antennas. Therefore, it is becoming a trend to effectively fuse different antennas. However, the current fusion method can significantly increase the windward area of the antenna, so that optimization is needed. Disclosure of Invention The application provides an antenna system and communication equipment which can effectively reduce the windward area and are convenient for flexible collocation. In one aspect, the present application provides an antenna system including a first antenna and a second antenna. The first antenna comprises a first antenna housing, a first radiating component and a feed network, and the second antenna comprises a second antenna housing and a second radiating component. The first antenna cover has a first outer surface with a recess. The first radiation assembly is disposed within the first antenna housing for transmitting or receiving electromagnetic waves. The feed network is connected to the first radiating element such that the feed network feeds signals to the first radiating element with a certain amplitude, phase. In addition, the feed network is disposed in the first antenna cover and located at a side of the groove. In addition, the second radome has a second outer surface, the second radiation assembly is disposed within the second radome, and at least a portion of the second outer surface may extend into the recess. In the antenna system provided by the application, the first antenna and the second antenna are two mutually independent antennas, the two antennas can be independently used, and the two antennas can be combined for use. When the two antennas are combined, the thickness dimension is not obviously increased, so that the windward area is reduced, and the use safety is improved. Specifically, since the first antenna cover has a groove, and the second outer surface of the second antenna cover can extend into the groove, when the first antenna and the second antenna are combined, the overall thickness is smaller than the sum of the thicknesses of the first antenna and the second antenna, and therefore, the thickness dimension of the whole antenna system is reduced. In addition, because the feed network is arranged at the side part of the groove, electromagnetic waves generated by the feed network can not obviously influence the normal operation of the second radiation component in the second antenna, and the normal operation performance of the second antenna is guaranteed. In one implementation, the first antenna may further include a first frequency selective surface. The first frequency selective surface is located between the first radiation assembly and the second radiation assembly for reflecting signals of the first radiation assembly and transmitting signals of the second radiation assembly. Electromagnetic waves generated by the first radiating assembly propagate through the first frequency selective surface in a direction away from the first frequency selective surface. In addition, when a part of electromagnetic waves propagate to the first frequency selective surface, the electromagnetic waves can be reflected by the first frequency selective surface, so that the propagation efficiency of the first radiation component can be effectively improved. In addition, electromagnetic waves generated by the second radiation assembly can effectively propagate through the first frequency selective surface, so that the normal working performance of the second radiation assembly is not affected. When specifically arranged, the projections of the first radiation component on the first frequency selection surface can be all located in the first frequency selection surface, so that the first frequency selection surface can have good reflection effect on electromagnetic waves generated by the first radiation component. In one implementation manner, the projection of the feeding network on the second radiation component may be located outside the second radiation component, so that adverse effects such as blocking of electromagnetic waves generated by the second radiation component by the feeding network can be effectively prevented. In one implementation, the first antenna may further include a third radiation component, where an operating frequency band of the thi
