Slot antenna.
Background technology
Slot antenna is the antithesis antenna of element antenna, has a wide range of applications.But, common slot antenna not only spoke
Penetrate the length of the line of rabbet joint itself and to have 1/2nd wavelength, and radiate and also need to bigger Metal ground around the line of rabbet joint and amass, logical
Often length 1/2nd wavelength bigger than the length of the line of rabbet joint on metal ground, the width big 1/2nd of the width ratio line of rabbet joint on metal ground
Wavelength.Multipolarization MIMO can effectively improve spectrum efficiency and channel capacity, in order to be applied by MIMO technology
To the terminal that volume is little, need co-located for the most like-polarized antenna placement.The radiation of antenna can be produced by bigger metal ground
Occlusion effect so that slot antenna is not suitable for co-located multiple-input and multiple-output (MIMO) application, in particular as multipolarization
When antenna uses, big metal ground will cause the isolation between the cross polarization variation of antenna, antenna port to be deteriorated, these
All will cause the decline of spectrum efficiency and channel capacity.The impedance of the line of rabbet joint simultaneously is very big, also makes slot antenna feeding transmission
The impedance matching of line is relatively difficult.The development of modern communications simultaneously also requires that antenna can be with multiband operation and two frequencies
Band can regulate respectively.

Metal ground connects.
Change the thickness of medium substrate, pcrmeability and dielectric constant, thus it is possible to vary the characteristic resistance of the high resistant line of rabbet joint and the low-resistance line of rabbet joint
Anti-, change the height impedance ratio of the Stepped Impedance radiation line of rabbet joint, and then change the low frequency operation frequency band of antenna operating frequency and
The operating frequency of high-frequency work frequency band.
Change the length of the low-resistance line of rabbet joint, low-resistance line of rabbet joint position in the radiation line of rabbet joint, the electrical length of the radiation line of rabbet joint can be regulated,
To realize antenna miniaturization in various degree, it is also possible to change operating frequency and the high-frequency work of the low frequency operation frequency band of antenna
The operating frequency of frequency band.
Change grid seam in adjacent gate seam spacing, grid seam width, grid seam short-circuit end from radiation the line of rabbet joint distance, Ke Yigai
The change of weather operating frequency of line, the width of working band and the electrical length of the radiation line of rabbet joint.
Change the width of the radiation line of rabbet joint, the low-resistance line of rabbet joint and the characteristic impedance of the high resistant line of rabbet joint can be regulated, change Stepped Impedance spoke
Penetrate the height impedance ratio of the line of rabbet joint, and then change operating frequency and the work of high-frequency work frequency band of the low frequency operation frequency band of antenna
Frequency.
The electrical length of grid seam should not be taken at 1/4th, to avoid causing resonance radiation, causes cross-polarized rising.
The operating frequency of the low frequency operation frequency band of three polarization slot antennas of grid seam ground coaxial feed low-resistance sidewall Stepped Impedance
Mainly determined by the resonant frequency of the radiation line of rabbet joint with the operating frequency of high-frequency work frequency band, but the size on metal ground, coaxial
The operating frequency of antenna and matching degree can also be adjusted by the position that feeder line inner wire is connected with the radiation line of rabbet joint.Due to
The radiation line of rabbet joint existing low-resistance line of rabbet joint has again the high resistant line of rabbet joint, constitutes the radiation line of rabbet joint of Stepped Impedance, not only makes antenna small-sized
Change, reduce cross polarization, also reduce the size on metal ground, improve isolation and reduce the occlusion effect on metal ground,
But also so that antenna has multiple working band, and change the low-resistance line of rabbet joint and the relative length of the high resistant line of rabbet joint and impedance,
The position of two working bands can be adjusted respectively.Radius slit is become periodically to load, again by metal grid seam on the ground
Make to radiate the line of rabbet joint and become periodic slow-wave structure, further reduce the electric size of antenna；Simultaneously because the side of grid seam
To vertical with the direction of the radiation line of rabbet joint, it is suppressed that metal is on the ground along the electric current in radiation line of rabbet joint direction, and makes along radius
The more concentration of the remaining CURRENT DISTRIBUTION in seam direction, thus reduce cross-polarized radiation, improve between antenna port
Isolation, also reduce metal ground size, reduce metal ground occlusion effect.
