Description

Technical Field

[0001] The utility model relates to the technical field of antenna bases, in particular to a mounting base for an antenna. Background Art

[0002] An antenna is a converter that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium (usually free space), or vice versa. A component used to transmit or receive electromagnetic waves in radio equipment. Engineering systems such as radio communications, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, all of which use electromagnetic waves to transmit information, rely on antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, non-signal energy radiation also requires antennas. Generally, antennas are reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna. The basic characteristic parameters of the same antenna as a transmitter or receiver are the same. This is the reciprocity theorem of the antenna. When setting up the antenna, a mounting base is required to provide stable support.
