Background technique
Yagi aerial be by an active dipole (generally with folded dipole), a passive reflector and several passive draw
To device it is arranged in parallel made of end-fire antenna.In the twentieth century twenties, by the Yagi spark gap show time of northeastern Japan university and space field
This antenna is illustrated in two human hair of Tai Lang, referred to as " Uda antenna ", referred to as " yagi aerial ".
The working principle of yagi aerial is such (by taking three-element aerial receives as an example): director is slightly shorter than half
Wavelength, main element are equal to half wavelength, and reflector is slightly longer than half wavelength, two element spacing quarter-waves.
At this point, director to inductive signal be in " capacitive ", 90 ° of electric current leading voltage；The electromagnetic wave of director induction can be to main element spoke
It penetrates, radiation signal counteracts its 90 ° of lag just caused by front " advanced " by quarter-wave distance, the two phase
Position is identical, and then signal superposition, is strengthened.Reflector is slightly longer than half wavelength, in perception, 90 ° after current hysteresis, then plus
On be radiated during main element 90 ° of lag again, it is 180 ° just poor that the two adds up, and plays negative function.One direction adds
By force, a direction weakens, and there has been highly directive.Emission state mechanism.
Currently, many areas receive wireless signal with yagi aerial ontology, in order to obtain good reception, often need
Will the reception position to yagi aerial ontology be adjusted.But existing yagi aerial ontology receives position and side selected
Backward, be directly anchored to installation place, when needing to adjust later, fixed again after can only removing again, and in multiple times remove and
Yagi aerial ontology is installed, is easy to make its damage, reliability is poor.
