B4705CN

RF Antennas are a class of specialized antennas used for transmitting and receiving electromagnetic radiation in the radio frequency (RF) range. The RF Antennas B4705CN is one of the most popular antennas used in numerous RF applications, due to its versatile design and advanced capabilities. This article will look into the RF Antennas B4705CN application fields and working principle.

Application Field

The RF Antennas B4705CN can be used in a variety of applications, including but not limited to satellite communications, wireless video and voice communications, wireless security surveillance, digital television and digital audio broadcasting. The antenna features a wide frequency range which covers frequencies from 0.7 GHz to 12.75 GHz.

The B4705CN antenna is especially suitable for use in multi-frequency and multi-operator systems such as VSAT, GSM/CDMA/UMTS/WCDMA/TD-SCDMA/WiMAX and 2.45GHz/5.7GHz/7.2GHz wireless LAN systems. Its high gain and low VSWR make it an ideal choice for high-power systems.

Working Principle

The RF Antennas B4705CN is a high gain, dual-polarity waveguide horn antenna. The antenna is constructed from high-quality aluminum alloy and consists of two orthogonally mounted waveguides. The inner waveguide is corrugated to reduce side and rear lobes. The waveguide antenna is connected to a balun, which is used to convert the balanced feed from the waveguide to the unbalanced feed from the transmitter/receiver.

In operation, the antenna receives energy as an incident wave in the transverse electromagnetic (TEM) mode. The wave is reflected off the inner surface of the waveguide and converted into an electric field by the antenna. This electric field is then emitted into the environment as a radiated field in the form of an electromagnetic wave. The outer surface of the waveguide is used to reduce losses.

The dual linear polarizations of the B4705CN antenna enable it to transmit and receive signals in both the X and Y planes. This makes it ideal for use in multiple channels and multiple operator systems. It also has excellent radiation characteristics and is capable of transmitting a highly directive signal even when used in a multi-polarized system.

Conclusion

The B4705CN antenna is a versatile and reliable device that provides excellent performance in a wide range of RF applications. Its wide frequency range and dual linear polarizations make it an ideal choice for use in multiple channels and multiple operator systems. Its strong signal power and low VSWR make it a great choice for high-power systems as well.
