Broadband receiving system

Technical Field

Background

An antenna is a transducer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space) or vice versa. A component for transmitting or receiving electromagnetic waves in a radio device. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, radio astronomy and the like all use electromagnetic waves to transmit information and work by depending on antennas. In addition, in transferring energy with electromagnetic waves, non-signal energy radiation also requires antennas. The antennas are generally reciprocal in that the same pair of antennas can be used as both transmit and receive antennas. The same antenna is the same as the basic characteristic parameter for transmission or reception. This is the reciprocity theorem for antennas.

At the transmitting end, modulated high-frequency oscillation current (energy) generated by a transmitter is input into a transmitting antenna through a feed device (the feed device can directly transmit current waves or electromagnetic waves according to different frequencies and forms), and the transmitting antenna converts the high-frequency current or the guided wave (energy) into radio waves, namely free electromagnetic waves (energy) which are radiated to the surrounding space (see fig. 1); at the receiving end, the radio waves (energy) are converted into high-frequency currents or guided waves (energy) by the receiving antenna, and are transmitted to the receiver through the feed device. From the above process, it can be seen that the antenna is not only a device for radiating and receiving radio waves, but also an energy converter, which is a device for interfacing between the circuit and the space.

However, the antenna direction in a single direction has a poor receiving capability for a specific signal, so that a system for self-selecting the preferred antenna direction is provided, and self-evaluation is performed on different signals so as to obtain a good receiving angle.
