Problems solved by technology

[0003] Early antenna testing mainly relied on manual work, with large errors and low efficiency. With the development of computer science and technology, an automatic control system for antenna testing has emerged. Practice and small-scale antenna engineering tests require antenna test systems, and the cost is high and the development cycle is long, so its market scope is small

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to an automatic test system for antenna pattern. Background technique [0002] The so-called antenna pattern refers to the graph of the relative field strength (normalized modulus) of the radiation field changing with the direction at a certain distance from the antenna. Usually, two mutually perpendicular plane patterns in the maximum radiation direction of the antenna are used. To indicate that the antenna pattern is an important graph to measure the performance of the antenna, and various parameters of the antenna can be observed from the antenna pattern. [0003] Early antenna testing mainly relied on manual work, with large errors and low efficiency. With the development of computer science and technology, an automatic control system for antenna testing has emerged. Practice and small-scale antenna engineering tests require antenna test systems, and the cost is hi...
