Technical field
The present invention relates to a kind of flat plane antenna, especially a kind of individual layer multifrequency two radiator antenna.
Background technology
Flat plane antenna is conventional antenna, with the characteristic such as simple structure, easy to process.Flat plane antenna typically has the line of rabbet joint day
Line and the major class of paster antenna two.Slot antenna is the antithesis antenna of element antenna, is omnidirectional radiation.But, the common line of rabbet joint day
The length that line not only radiates the line of rabbet joint will have 1/2nd wavelength, and larger Metal ground product is also needed to around the radiation line of rabbet joint.
Larger metal ground can cause that slot antenna is not suitable for multiple-input and multiple-output (MIMO) and applies, and cause the cross polarization of antenna to become
Difference, these will all cause the decline of spectrum efficiency and channel capacity.The impedance of the line of rabbet joint is very big simultaneously, also causes slot antenna feed
The impedance matching of transmission line is relatively difficult.Paster antenna is due to the presence of ground plane, and its radiation is main to the side for being partial to paster.
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.
It is still a problem for challenge how slot antenna and paster antenna to be combined, and is particularly realized with single layer substrate
The development of even more difficulty, and modern communicationses does not require nothing more than antenna and can also require that multiple frequency bands can be respectively with multiband operation

Individual layer multifrequency two radiator antenna has the radiation line of rabbet joint and the single radiator of radiation patch two, and these radiators are total to
With a feed port.The working frequency of the radiation line of rabbet joint and radiation patch influences each other very little, therefore can be with separately adjustable radiation
The working frequency of the line of rabbet joint, it is also possible to the working frequency of separately adjustable radiation patch.
The radiation line of rabbet joint is omnidirectional radiation, has primary radiation in the both sides of medium substrate, its low frequency line of rabbet joint working band and height
Frequency line of rabbet joint working band is mainly determined by the resonant frequency of the radiation line of rabbet joint, but size, the microstrip feed line conduction band on metal ground are in spoke
Penetrating the impedance of the position, microstrip feed line of the line of rabbet joint, microstrip feed line terminal can also be to the work of antenna frequently with a distance from the radiation line of rabbet joint
Rate and matching degree are finely adjusted.Because 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 so that antenna miniaturization, also reduces the size on metal ground, and cross polarization is also reduced, and be also possible that day
Line has multiple working bands.
