RF Antennas are essential in communication systems, and they are the interface between the physical layer and the air. As the development of radio technology, antenna has become more and more important in the fields of wireless communication, navigation and radio astronomy. The Antenna pattern (ANT-P) application field is a special field of radio antennas which is widely used in the industries such as microwave communication, navigation and broadcasting. In this paper, the working principle and application field of ANT-P will be introduced in detail.

The working principle of ANT-P is based on the direction of energy radiation analysis. When electromagnetic radiation meets a plane, it will form certain energy radiation characteristics. According to this characteristic, the ANT-P can determine the direction of the radiated energy and the coverage of the antenna. The ANT-P can measure the parameters of the antenna, including the magnitude of the antenna gain, the radiation direction, the sidelobe level, the cross-polarization ratio and the 3-dB beamwidth, etc. These parameters are important for judging the characteristics of the antenna, and they are of great significance for the optimization of the antenna.

The application fields of ANT-P include telecommunications, broadcast, navigation, radio astronomy and wireless communication. In the telecommunication field, ANT-P is mainly used to measure the performance of the antenna and to evaluate the coverage of communication systems. For example, in a GSM mobile communication system, the ANT-P can determine the coverage radius of the system by measuring the magnitude of the radiation field strength. Besides, in the navigation field, ANT-P can be used to measure the direction of the navigation signal and the coverage of the navigation system. In the radio astronomy field, the ANT-P can measure the characteristics of various antennas such as the polarization, direction of radiation and beamwidth.

In a word, the Antenna pattern (ANT-P) application field is a special field of radio antennas, and it plays an important role in telecommunications, navigation and radio astronomy. The ANT-P can measure various parameters of the antenna and determine its characteristics, which is significant in optimizing the performance of the antenna. Therefore, the ANT-P is widely used in the communication systems and navigation systems.
