RF antennas have wide application field and different working principles. This paper focuses on one kind of antenna, BB1323R, which is widely used in wireless communication and satellite communication.

Application Field of BB1323R

The BB1323R antenna is an omni-directional antenna with dual frequency options for operation at 900 MHz and 1.3GHz. Due to its significant receiving sensitivity and radiation power, it is a major product of high-end markets. Broadly speaking, the applications of BB1323R cover a wide range ranging from long range applications to short range applications. The common applications and scenarios are as follows.

• Long-range applications: wireless telecommunication, broadcast and satellite communication with gain up to 33 dbi.
• Short-range applications: Point-to-Point, Point-to-Multipoint for home routers, Video Surveillance, Data transmission and more.
• Other situations: Wireless bridges (WLAN), Wifi Hot Spot and Wireless Symphony sites.

Working Principle of BB1323R

The working principle of BB1323R is the same as that of other antennas. The frequency effect comes from the fact that the setup of the antenna and the length of the antenna drive the signal to a specific frequency when the force is applied. It is important to select the proper material and shape for the antenna to fit the desired frequency range. The major components of the BB1323R antenna are four parts: antenna reflector, antenna ground plane, radiating element and the power divider.

Antenna Reflector

The antenna reflector is usually used to reflect energy towards the desired direction and reduce the unwanted radiation loss and to focus the transmitted radio signal. The design of the antenna reflector depends on the frequency range and transmission distance. The reflector usually consists of a metal sheet that is designed in specific manner in order to increase the gain and range of the antenna.

Antenna Ground Plane

The antenna ground plane is used to provide stable and uniform radiation pattern and to increase the gain of the antenna. The ground plane usually consists of a conductive plate that is placed at, or slightly below the ground level. It helps to reflect the energy back and forth in a specific direction in order to increase the transmission range of the antenna.

Radiating Element

The radiating element is the most important component of an antenna. It is responsible for receiving and transmitting the radio signals. Its design usually depends on the frequency range of the antenna. The radiating element used in the BB1323R antenna is composed of a dipole that is designed to match the desired frequency range.

Power Divider

The power divider is used to divide the signal into multiple components and direct them towards different directions. The power divider consists of a piece of insulating material that is designed to divide the input signal into two parts. This is useful for multi-directional antennas that require a single power source.

Conclusion

The BB1323R antenna is a major product of high-end markets, suitable for use in various scenarios such as long-range applications, short-range applications and other situations. The working principle of BB1323R is mainly composed of the antenna reflector, antenna ground plane, radiating element and the power divider, each of which play a major role in making the antenna work effectively.
