Introduction

YA9-13 is a type of RF antenna, which is designed to transmit and receive radio signals. It is primarily used in the military, as well as the civilian application. It is particularly useful for high-frequency applications because of its low noise figure, wide bandwidth, and high gain. This article will discuss the application field and working principle of YA9-13.

Application Field

The YA9-13 antenna is designed to operate in the frequency range of 9–13 GHz, which is commonly used in military and civilian applications. In the military, YA9-13 is used for various purposes, such as long-range communication, monitoring, base station communication, and intelligence gathering. On the other hand, in the civilian field, YA9-13 is primarily used by satellite operators for uplink and downlink. It is also used in radio measurements, Wi-Fi, and other wireless applications.

Working Principle

YA9-13 antennas use a combination of parabolic reflector and horn radiating elements to achieve their desired performance. The reflector consists of a parabolic surface made of aluminum or steel, and the horn radiating element consists of a small antenna located at the center of the flare. The antenna is connected to a radiofrequency feedline, that transmits or receives signals depending on the desired use.

When a signal is emitted, it is directed by the horn radiating element towards the parabolic reflector. The parabolic reflector captures the signal and reflects it in a single direction. This helps the signal to travel long distances without loss of power. The same is done in the reception of signals. A signal travelling from the source is captured by the antenna and directed towards the parabolic reflector, which reflects it back to the feedline.

Conclusion

YA9-13 is a type of RF antenna, which is designed to transmit and receive radio signals in the frequency range of 9–13 GHz. It is primarily used in military and civilian applications, such as long-range communication, monitoring, and intelligence gathering. The antenna uses a combination of parabolic reflector and horn radiating elements to achieve its desired performance. The parabolic reflector helps the signal to travel long distances without loss of power.
