It should be noted that oscillator arms are designed as round or heart by the oscillator of the application, compared with existing oscillator,
Round or heart-shaped oscillator arms, can provide longer radiation arm equivalent electrical length, also, be applied in smaller space
When multifrequency antenna, oscillator arms radiation direction becomes horizontal direction and vertical direction.Therefore, under identical radiation effect, a side
Oscillator can be accomplished smaller by face, smaller oscillator in multifrequency antenna, each other interfere with each other and couple smaller；Separately
On the one hand, since oscillator arms radiation direction changes, the distance between oscillator can be designed smaller, and mutually dry without worrying
It disturbs and couples；So that the width of multifrequency antenna can make it meet the use of miniaturization and design requirement with smaller.
Preferably, by insulating materials support, there are one metallic parasitic pieces on the top of folded dipole, are used for coupling bandwidth.
Preferably, metallic parasitic piece is round or rectangular.
Preferably, in the space of pierced pattern, the side wall of folded dipole arm extends towards out metal at symmetric position
Branched structure, metal branch structure form bandwidth match slot.
It should be noted that the purpose of metal branch structure is also in limited space, further extend radiates
The equivalent electrical length of arm adjusts bandwidth.
Preferably, folded dipole and oscillator pillar are integrally formed.
It should be noted that folded dipole and the integrated molding of oscillator pillar can reduce part, assembly welding is reduced, in turn
Reduce the various defects caused by assembly welding.
Due to using the technology described above, the advantageous effect of the application is：
The broadband novel oscillator of the application, oscillator arms is designed as round or heart-shaped, and four oscillator arms join end to end composition
Folded dipole, round or heart-shaped oscillator arms, can provide longer radiation arm equivalent electrical length in smaller space, because
Oscillator can be accomplished smaller by this under identical radiation effect.Also, the oscillator of the application changes the radiation of oscillator arms
Direction, oscillator arms radiation direction become horizontal direction and vertical direction so that and the distance between oscillator can be designed smaller, and
Without worrying to interfere with each other and couple.Therefore, when the oscillator of the application is used for multifrequency antenna, multifrequency antenna can effectively be reduced
Width, make multifrequency antenna smallerization.
