Introduction

QW220 is a RF (radio frequency) antenna, it is a compact 2-element antenna designed for dual-band operation in the 2.3 GHz and 5.5 GHz range. It is an ideal choice for modern applications that require reliable wireless communication at both short and long distances. The antenna is light and robust, and is designed to perfom in all weather conditions.

Application Field

QW220 antennas are widely used in many applications such as Baby Monitors, CCTV security cameras, UAVs (Unmanned Aerial Vehicles) and Drones, Marine Navigation Systems, Wireless Communication Networks.QW220 antennas are ideal for both short, long-distance communication, and line-of-sight applications in low- or medium-data rates, such as for transmitting video or images. The antenna is also resilient to interference from nearby radio sources, making it perfect for military and security operation environments with multiple radios. In addition, its low-profile design helps reduce obstruction of view as well as reduce wind-load on UAVs and drones.

Working Principle

At the heart of the QW220 antenna design is the use of two active element elements: a reflector and a director. The reflector element uses a specially designed metal plate to help focus the outgoing signal in a single direction. The director element also uses another reflective metal plate to help direct and focus the outgoing signal in that same direction.Together, the two elements work together to direct the outgoing signal in one direction. This helps reduce losses in the antenna, and also minimizes interference from nearby sources.The QW220 antenna also supports the use of dual-band transmitters, allowing it to transmit signals in both the 2.3 GHz and 5.5 GHz range. This offers a vast amount of channels and data rates depending on the type of application.

Conclusion

QW220 is a dual-band RF antenna, designed for reliable wireless communication in the 2.3 GHz and 5.5 GHz range. The antenna is light and robust, and designed to perform in all weather conditions. It is widely used in many applications such as Baby Monitors, CCTV security cameras, UAVs, Marine Navigation Systems, Wireless Communication Networks. The working principle of the QW220 is based on the use of two active elements: a reflector and a director, which help direct and focus the outgoing signal in one direction. This reduces losses in the antenna, and minimizes interference from nearby sources.
