Abstract

The invention discloses a frequency modulation receiving antenna which comprises a top seat and a mounting base. The frequency modulation receiving antenna is characterized in that a motor is fixed atthe top of the mounting base; the top seat is fixed on the top end of a vertical rod; the top of the top seat is sleeved by a signal receiving cover through a connecting rod; first rollers are symmetrically rotatably arranged on both sides of the front wall of the top seat; a second roller is connected between two first rollers through a transmission hinge; the second roller is embedded in a dialfixed at the center of the front wall of the top seat; and the connecting rod is embedded in the inner side of the second roller. According to the invention, the first rollers drive the second rollerto rotate to enable the signal receiving cover which sleeves the top of the top seat to rotate, so as to automatically adjust the deflection angle of the signal receiving cover; the signal receivingcover in use can quickly find a position with a strong signal; and the frequency modulation receiving antenna has the advantages of convenient adjustment and high practicality.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a frequency modulation receiving antenna. Background technique [0002] An antenna is a transformer that transforms 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 used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, 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 ...
