RF Antennas
The DP-900 is a type of RF (radio frequency) antenna, also known as dipole antenna. It is one of the most used types of antenna due to its easy installation, low cost and good electromagnetic properties. It is mainly used in radio communication systems such as FM (frequency modulated) broadcasting and wireless local area networks (WLAN).
Application Fields of DP-900
The DP-900 antenna is mainly used for broadcast and communication purposes. It is especially suitable for broadcast stations due to its high efficiency. It can broadcast RF signals over long distances with high reliability. It is also widely used in WLAN systems, where it can increase signal coverage range and provide better client services. Besides, it can also be used in wireless video broadcasting, radio navigation and military communication systems.
Working Principle of DP-900
The DP-900 antenna is a bi-directional antenna, meaning that it can transmit radio signals in both directions. It utilizes two half-wave radiators (also known as dipoles) arranged in a straight line. Each dipole is excited by the same electric field, which causes the oppositely charged particles in the dipole to move in the same direction. This creates a standing wave of electromagnetic energy, which is then radiated out from the antenna.
The radiation pattern of the DP-900 antenna is omnidirectional. This means that it is able to broadcast signals to all directions without having to move the antenna. Additionally, the antenna has a low SWR (Standing Wave Ratio) which means that it can operate at a wide range of frequencies. It also has low loss, making it suitable for long-distance communication.
Conclusion
In conclusion, the DP-900 antenna is an omnidirectional antenna that is suitable for broadcast and communication applications. It has low cost, low loss and wide range of operation, making it one of the most widely used antennas in the RF industry.
