What Is The Car Satellite TV Antenna

What is the Car Satellite TV Antenna
A satellite satellite television antenna is a converter that converts a traveling wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. A component used in a radio to transmit or receive electromagnetic waves. Radio communication, radio, television, radar, navigation, electronic warfare, remote sensing, radio astronomy and other engineering systems, all use of electromagnetic waves to transmit information, rely on Car Satellite TV Antenna to work. In addition, in the use of electromagnetic waves to transmit energy, non-signal energy radiation also need Car Satellite TV Antenna. General Car Satellite TV Antenna is reversible, that is, the same Car Satellite TV Antenna can be used as a radio satellite TV antenna, can also be used to receive Car Satellite TV Antenna. The same Car Satellite TV Antenna as the basic characteristic of transmitting or receiving parameters is the same. This is the reciprocity theorem of the Car Satellite TV Antenna.
Car Satellite TV Antenna radiation is a radio wave, the radio is also received, but the transmitter through the feeder into the Car Satellite TV Antenna is not a radio wave, to receive the Car Satellite TV Antenna can not be directly into the radio by the feeder cable , Which must go through the energy conversion process. Here we take a radio communication equipment as an example to analyze the signal transmission process, and then explain the Car Satellite TV Antenna energy conversion.
At the transmitter, the modulated high-frequency oscillating current (energy) generated by the transmitter is transmitted by the feeder device to the vehicle-borne satellite TV antenna (the feeder device can transmit current waves or electromagnetic waves with frequency and form) (See Figure 1); at the receiving end, the radio waves (energy) are converted to high by receiving a satellite satellite television antenna, which converts the high frequency current or wave (energy) into radio waves - free electromagnetic waves (energy) The frequency current or guided wave (energy) is transmitted to the receiver via a feeder device. From the above process can be seen, the Car Satellite TV Antenna is not only radiation and receive radio waves device, but also an energy converter, is the circuit and space interface devices.
