The low frequency operation frequency band of three polarization slot antennas of grid seam ground coplanar wave guide feedback low-resistance sidewall Stepped Impedance
Operating frequency and high-frequency work frequency band operating frequency mainly by radiation the line of rabbet joint resonant frequency determine, but golden
The position that the size in possession, coplanar waveguide feeder line conductor are connected with the radiation line of rabbet joint can also be to the operating frequency of antenna
It is adjusted with matching degree.Owing to the radiation line of rabbet joint existing low-resistance line of rabbet joint has again the high resistant line of rabbet joint, constitute step resistance
The anti-radiation line of rabbet joint, not only makes antenna miniaturization, reduces cross polarization, also reduces 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
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
Put.Metal grid seam on the ground becomes periodically loading to radius slit, makes again to radiate the line of rabbet joint and becomes periodically
Slow-wave structure, further reduce the electric size of antenna；Simultaneously because the direction of grid seam and the side radiating the line of rabbet joint
To vertically, it is suppressed that metal is on the ground along the electric current in radiation line of rabbet joint direction, and makes along radiating the surplus of line of rabbet joint direction
The more concentration of remaining CURRENT DISTRIBUTION, thus reduce cross-polarized radiation, improve between antenna port every
From, also reduce the size on metal ground, reduce the occlusion effect on metal ground.
