RF antennas are widely used in a variety of applications, such as wireless communications, broadcasting, satellite communications, navigation, radio astronomy, and so on. Among them, A5645 is a type of antenna with wide application scope, which is widely used in a large number of communication systems. The article will mainly talk about A5645 application field and working principle.

A5645 is multi-band antenna. It can be used in various communication systems, such as military and civilian systems. It can operate in a variety of frequency bands, including UHF, MB, EHF and so on. This makes A5645 very adaptable for various applications. Moreover, the antenna gain of A5645 is relatively high, which can provide excellent communication performance no matter the distance is long or short. That is why it is widely used in communication system.

A5645 mainly consists of three parts, feed network, flat reflector and antenna block. The feed network is the part that is electrically connected to the antenna block, and it provides the necessary electrical connection between the antenna and the load. It is also responsible for the transmission of power from the radio receiver and transmitter. The task of the reflector is to reflect the radio waves form the antenna block back to the antenna feed. In this way, the energy of the wave can be concentrated in one direction, thus improving the gain of the antenna. At last, the antenna block is the part connecting the feed network and the reflector, which is comprised of reradiating elements like dipole, slot, horns, etc.

Finally, the working principle of A5645 is very simple. The feed network will convert the radio waves coming from the radio receiver into electrical currents. These currents will then be passed on to the antenna block that will then reradiate the energy in the form of radio waves. The radio waves will then be bounced back by the reflector, and travel back to the feed network, completing the whole transmission process. That is why A5645 is so efficient and effective in communication systems.

In conclusion, A5645 is a multi-band antenna widely used in various communication systems. It is also characterized by high antenna gain and excellent performance. Its working principle is very simple and effective, making it an ideal choice for many communication systems. Therefore, A5645 is still one of the most widely used antennas in communication systems.
