Technical field
The present invention relates to a kind of flat plane antenna, especially a kind of single layer multifrequency two radiator antenna.
Background technique
Flat plane antenna is common antenna, has the characteristics such as simple structure and convenient processing.Flat plane antenna generally has line of rabbet joint day
Line and paster antenna two major classes.Slot antenna is the antithesis antenna of element antenna, is omnidirectional radiation.But common line of rabbet joint day
The length that line not only radiates the line of rabbet joint will have half wavelength, but also radiate and also need biggish Metal ground product around the line of rabbet joint.
Biggish metal meeting so that slot antenna be not suitable for multiple-input and multiple-output (MIMO) application, cause the cross polarization of antenna to become
Difference, these all will lead to the decline of spectrum efficiency and channel capacity.The impedance of the line of rabbet joint is very big simultaneously, also slot antenna is fed
The impedance matching of transmission line is relatively difficult.Paster antenna is radiated main to the side for being biased to patch due to the presence of ground plane.?
Slot antenna is combined with paster antenna, can not only be worked with multifrequency multi radiator, the radiation for also making full use of its different
Characteristic is application service, and in single common slot-coupled paster antenna or gap loaded patch antenna, gap is non-radiating.
How slot antenna and paster antenna are combined be still a challenge problem, especially realized with single layer substrate
It is even more difficult, and the development of modern communications does not require nothing more than antenna and can also require multiple frequency bands that can distinguish with multiband operation
It adjusts.
Summary of the invention
Technical problem: the purpose of the present invention is to propose to a kind of single layer multifrequency two radiator antenna, which is single medium base

Single layer multifrequency two radiator antenna has radiation two individual radiators of the line of rabbet joint and radiation patch, these radiators are total
With a feed port.The working frequency of the radiation line of rabbet joint and radiation patch influences each other very little, therefore separately adjustable can radiate
The working frequency of the line of rabbet joint, can also be with the working frequency of separately adjustable radiation patch.
Radiating the line of rabbet joint is omnidirectional radiation, has primary radiation, low frequency line of rabbet joint working band and height in the two sides of medium substrate
Frequency line of rabbet joint working band is mainly determined by the resonance frequency of the radiation line of rabbet joint, but the size on metal ground, microstrip feed line conduction band are in spoke
Penetrate the position of the line of rabbet joint, the impedance of microstrip feed line, microstrip feed line terminal from radiation the line of rabbet joint with a distance from can also to antenna work frequency
Rate and matching degree are finely adjusted.Since the radiation existing low-resistance line of rabbet joint of the line of rabbet joint has the high resistant line of rabbet joint again, the characteristic with Stepped Impedance,
Not only make antenna miniaturization, also reduce the size on metal ground, and also reduce cross polarization, and is also possible that day
Line has multiple working bands.
The operation wavelength of radiation patch is mainly determined that operation wavelength is about radiation patch length by the length of radiation patch
Twice.
The utility model has the advantages that the beneficial effect of single layer multifrequency two radiator antenna of the invention is that the antenna is single medium substrate,
It is at low cost；It can reduce the electric size of entire antenna, realize miniaturization, also there is the cross polarization effect for inhibiting antenna；Antenna
There are two the radiators for sharing a feed port, while the antenna not only has multiple frequency bands, but also multiple frequency bands can be distinguished
It adjusts.
