Description

Technical Field

[0001] The utility model relates to the technical field related to anti-interference antennas, in particular to a high-isolation miniaturized anti-interference antenna. Background Art

[0002] All information and non-signal radiation transmitted by electromagnetic waves rely on antennas to work. In order to improve the anti-interference ability, the antenna has developed from passive antenna to active antenna. In order to further improve the anti-interference ability in different directions, it has developed into array antenna form. However, due to the diverse use environments of anti-interference array antennas, there are diverse requirements for the structural size of anti-interference array antennas. Therefore, a high-isolation, miniaturized anti-interference antenna is needed.

[0003] The prior art has the following deficiencies: when the prior anti-interference array antenna is in use, the spacing between array elements is greatly reduced due to the influence of the overall structural size, which in turn causes the problem of poor isolation between array elements. When the anti-interference antenna is in use, it is often fixed in a certain position with bolts, which is inconvenient to adjust the angle of the anti-interference antenna, affecting the transmission of information by the anti-interference antenna. The array elements are fixed inside the antenna shell. When a certain array element fails, it will affect the transmission of information by the anti-interference antenna as a whole.
