Embodiment 1

[0049] refer to figure 1 , in this embodiment, there is one omnidirectional feed source 10, and there are two first directors 21, which are arranged on both sides of the omnidirectional feed source 10 along the first direction X. The distance between each first director 21 and the omnidirectional feeder 10 is set to be a quarter of the air wavelength of the frequency of the omnidirectional feeder 10 . The two first directors 21 can work in two modes: one is a non-radiating state, and the other is a radiating state.

[0050] There is only one omnidirectional feed 10, and if the first director 21 is set to a radiation state, the first director 21 interacts with the omnidirectional feed 10 to form a multi-beam energy coverage pattern. If the first director 21 is set in a non-radiating state, the first director 21 interacts with the omnidirectional feed 10 to form an elliptical energy coverage pattern.

[0051] Preferably, the number of omnidirectional feed sources 10 is m, and ...

Embodiment 2

[0053] The difference between the second embodiment and the first embodiment is that there are multiple omnidirectional feed sources 10, and this embodiment image 3 There are two omnidirectional feed sources 10 shown, and three first directors 21 . refer to image 3 , the working mode of two omnidirectional feed sources 10 will be described below, and the number of omnidirectional feed sources 10 increases compared with the first embodiment, which increases the energy coverage.

[0054] When the number of omnidirectional feed sources 10 increases, the working status among omnidirectional feed sources 10 will directly affect the overall coverage form, mainly having the following two working forms:

[0055] The first type is that the two omnidirectional feed sources 10 are weakly correlated working modes, that is, independent working forms, which mainly refer to working in the form of 2*2 MIMO technology, that is, two antenna units are independently connected to the system, an...

Embodiment 3

[0060] refer to image 3 , in the third embodiment, four omnidirectional feed sources 10 are set. The first director 21 and the omnidirectional feed source 10 are arranged at intervals in sequence. For the balanced application of the omnidirectional feed 10 , only an even number of feeds is set here. Of course, an odd number of feeds is still possible, but the degree of beam convergence formed will be different. Similarly, the four omnidirectional feed sources 10 here can form the working form of the weak correlation array and the strong correlation array, and can also be split into the working form of the weak correlation array and the strong correlation array combined in pairs, and its working principle is the same as aforementioned. In addition, the working principle of the first director 21 is the same as that described above.

Abstract

The invention relates to a communication antenna. The communication antenna comprises omnidirectional feed sources and a director group, wherein the number of the omnidirectional feed sources is at least one, and the omnidirectional feed sources are sequentially arranged in a first direction; and the director group comprises a plurality of first directors, and the plurality of first directors and the omnidirectional feed sources are arranged at intervals along the first direction. According to the invention, the omnidirectional feed sources can obtain an array circumferential energy coverage directional diagram under the action of the first directors, the energy coverage directional diagram is in oval coverage, the directive energy intensity of the omnidirectional feed sources can be improved, that is, gain improvement is achieved, and the long axis of the oval energy distribution directional diagram is perpendicular to the first direction. The communication antenna is especially suitable for communication between vehicles running on a road under the current intelligent networking in application, the communication distance between antennae in the front direction and the rear direction of a vehicle body is effectively improved while transverse communication is guaranteed in a lane, and meanwhile, the communication antenna can be expanded and applied to application of any similar scenes such as ship communication scenes in maritime affairs.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to a communication antenna. Background technique [0002] With the development of intelligent networking of automobiles, the application of V2X and 5G new technologies has become an inevitable trend in the future, which will increase the number of automotive antennas, and the networking of automobiles will increase the communication data and communication systems between vehicles. . The continuous improvement of the degree of automation of automobiles makes it necessary to strengthen the continuity of the communication during the driving of the automobile, especially the guarantee of the front and rear communication distances of the fast-moving automobiles becomes important and key, and it is also an unsolved problem for existing antennas in the industry. At the same time, it is necessary to maintain the normal connection of the loop communication, so a new technology an...
