Abstract
The utility model discloses a kind of multifrequency antenna.It comprises radiant panel, parasitic patch, connection paster, dielectric-slab, ground plate and coaxial line, dielectric-slab is provided with radiant panel, four limits of radiant panel connect paster by four and are connected with parasitic patch, dielectric-slab is arranged with ground plate, ground plate is also provided with the coaxial line be connected with distributing point, described distributing point is arranged in parasitic patch.The utility model changes the current path on radiant panel surface by parasitic patch, creates two new current paths, thus makes antenna have four resonance frequencys; Structure is simple, and feed conveniently achieves the multiple-frequency operation of antenna.
Description
Technical field
The utility model relates to field of antenna, is specifically related to a kind of multifrequency antenna.
Background technology
Along with the development need that Modern wireless communication is applied to low frequency end and front end, antenna miniaturization and broadband technology have become the primary factor of actual microstrip antenna designs.And in the mobile radio systems such as radar, guidance, satellite communication, need antenna to realize multiple-frequency operation, current multifrequency antenna exists following defect: complicated structure, and the multifrequency bandwidth of antenna is usually all narrow, and result of use is not good.
Summary of the invention
For solving the problem, the utility model provides a kind of multifrequency antenna, and structure is simple, and feed conveniently achieves the multiple-frequency operation of antenna.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of multifrequency antenna, comprise radiant panel, parasitic patch, connection paster, dielectric-slab, ground plate and coaxial line, dielectric-slab is provided with radiant panel, four limits of radiant panel connect paster by four and are connected with parasitic patch, dielectric-slab is arranged with ground plate, ground plate is also provided with the coaxial line be connected with distributing point, and described distributing point is arranged in parasitic patch.
As preferably, described parasitic patch is strip metal patch.
As preferably, the length of described parasitic patch is consistent with the length of radiant panel.
The utility model has following beneficial effect: the current path being changed radiant panel surface by parasitic patch, creates two new current paths, thus makes antenna have four resonance frequencys; Structure is simple, and feed conveniently achieves the multiple-frequency operation of antenna.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the end view of Fig. 1.
Embodiment
In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1-2, the utility model embodiment provides a kind of multifrequency antenna, comprise radiant panel 1, parasitic patch 2, connect paster 3, dielectric-slab 4, ground plate 5 and coaxial line 6, radiant panel 1 is provided with in dielectric-slab 4, four limits of radiant panel 1 connect paster 3 by four and are connected with parasitic patch 2, dielectric-slab 4 arranged outside has ground plate 5, ground plate 5 is also provided with the coaxial line 6 be connected with distributing point 7, and described distributing point 7 is arranged in parasitic patch 2.
It should be noted that described parasitic patch 2 is strip metal patch.
In addition, the length of described parasitic patch 2 is consistent with the length of radiant panel 1.
This embodiment is by carrying out sheet metal loading processing to the radiating side of microstrip antenna radiant panel, effectively can reduce the resonance frequency of microstrip antenna, and realize the two-frequency operation characteristic of antenna, and at the non-radiant edged metal-loaded sheet of radiant panel, to realize the multiple-frequency operation performance of antenna.
This embodiment changes the current path on radiant panel surface by parasitic patch, creates two new current paths, thus makes antenna have four resonance frequencys; Structure is simple, and feed conveniently achieves the multiple-frequency operation of antenna.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
