Description
Technical Field
The utility model relates to the field of communication technology, especially, relate to a paster antenna array and communication system.
Background
A patch antenna array is an antenna composed of a plurality of patch antenna elements. Either fixed beam array antennas or phased array antennas. Because the distance between the antenna units is close, usually about half wavelength, strong mutual coupling exists between the units, and the coupling from different units around to a certain investigation unit has different amplitudes and phases. When most of the coupling fields are superimposed with substantially similar phases, the array will experience a large active impedance mismatch, resulting in large reflections and reduced array radiation performance.

Detailed Description
The invention will be further explained and explained with reference to the drawings and the embodiments in the specification. The step numbers in the following embodiments are provided only for convenience of illustration, the order between the steps is not limited at all, and the execution order of each step in the embodiments can be adapted according to the understanding of those skilled in the art.
Referring to fig. 1, an embodiment of the present invention provides a patch antenna array, including:
the patch antenna units 101 are M × N, the patch antenna units 101 are arranged in an M × N matrix, and M and N are integers greater than or equal to 2;
an opening 103, the opening 103 is disposed on the isolation wall 102.
In this embodiment, the openings 103 are formed in the isolation walls 102 between the patch antenna units 101, and a part of metal of the isolation walls 102 is removed, so that the coupling phases between the units in different directions can be changed, and the active reflection of the array can be greatly improved by selecting an appropriate slot width and an appropriate thickness of the isolation walls 102 according to needs.
In one embodiment, the isolation wall 102 is further provided with a plurality of vias 104.
In one embodiment, the opening 103 is filled with a dielectric material.
In this embodiment, the metal isolation wall 102 between the patch antenna units 101 may be a solid metal structure, or may be composed of a metalized via 104 and a strip line as shown in fig. 2. The grooving of the isolation wall 102 means that a part of metal of the isolation wall 102 is removed, and the removed space can be filled with a medium, and can also be air or vacuum.
In one embodiment, the isolation wall 102 is a metal isolation wall 102.
Furthermore, the embodiment of the utility model provides a communication system, including the paster antenna array that the basic station reaches, the basic station passes through paster antenna array transceiver signal.
As shown in fig. 3, fig. 3 shows a situation of superimposing several coupling vectors of the patch antenna array when the isolation wall 102 is not provided with the opening 103 in the prior art, and it can be seen that the resultant vector is larger, corresponding to a larger active reflection of the array; in the embodiment, after the opening 103 is formed in the partition wall 102, the resultant vector of the coupling vectors is significantly reduced, as shown in fig. 4, the active reflection of the array is greatly improved, and the radiation performance is significantly improved.
As can be seen from the above, the present invention provides a patch antenna array and communication system, which can effectively reduce the coupling between the patch antenna units 101 by providing the opening 103 on the isolation wall 102, thereby improving the active reflection of the antenna array and greatly improving the radiation performance.
While the preferred embodiments of the present invention have been described, the present invention is not limited to the embodiments, and those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are intended to be included within the scope of the present invention as defined by the appended claims.
