1.Production Introduction
Waveguide Tube is used to transmit ultra-high frequency electromagnetic waves. Through it, pulse signals can be transmitted to the destination with minimal loss. It is a hollow metal conduit with very smooth inner wall or a tube coated with metal; The inner diameter of the waveguide varies with the wavelength of the transmitted signal; It is mainly used in radio communication, radar, navigation and other radio fields of centimeter wave and millimeter wave. At present, the common Waveguide Tube are rectangular waveguide, circular waveguide, semicircular waveguide, Ku wave waveguide, radar waveguide and optical waveguide.
Working principle:
Different from the GSM-R mode used for bidirectional transmission of train ground wireless signals in the national high-speed railway signal system, directional antennas are mostly used in subway signals Leaky cable and slotted waveguide mode "Among the above three modes, the slotted waveguide mode is widely used because of its transmission frequency bandwidth, low transmission loss, high reliability and strong anti-interference ability.
For example, this mode is adopted for the bidirectional transmission of vehicle ground wireless signals in the signal system of Shanghai metro line 16, which was initially put into operation at the end of 2012. The waveguide can be divided into ordinary waveguide and slotted waveguide. Ordinary waveguide is a hollow metal conduit with a very smooth inner wall Or a tube with metal inside. The waveguide is used to transmit UHF electromagnetic waves.
The common cross-section shapes are rectangular and circular. Through it, the pulse signal can be transmitted to the destination with minimal loss. The inner diameter of the waveguide varies with the wavelength of the transmitted signal. The waveguide presents the characteristics of high pass filter in the circuit: the signal above the cut-off frequency is allowed to pass through, while the signal below the cut-off frequency is blocked or attenuated.
