Embodiment
This antenna is comprised of oscillator, subfeeder, main feeder and reflected bottom plate.
Oscillator comprises horizontal dipole 1 vertical dipole 2, and main feeder 7 is connected connections by subfeeder 4 with vertical dipole, and main feeder 8 passes through subfeeder 3 is connected connection with horizontal dipole.
Because horizontal dipole 1 and vertical dipole 2 all are comprised of two microstrip antennas, so also be provided with two one-to-two power splitters, wherein main feeder 7 through one-to-two power splitters 5 by two subfeeders 4 respectively with are connected a vertical microstrip antenna of placing and connect, main feeder 8 through one-to-two power splitters 6 by two subfeeders 3 respectively with are connected the microstrip antenna of a horizontal positioned and connect.
Wherein microstrip antenna is application for a patent for invention number: improvement 201010238411.6, patent name: " a kind of microstrip antenna "), the microstrip antenna that uses among the present invention for the feed transducer part calibration size of the tube-in-tube structure of each microstrip antenna in 1/4th of the centre wavelength of 2400-2500MHz.
The signal of horizontal and vertical polarization passes through main feeder, through two one-to-two power splitters, then feed is transferred to the antenna oscillator that horizontal and vertical is placed to subfeeder, pass through again reflection and the figuration effect of reflected bottom plate, form respectively the signal of horizontal polarization and perpendicular polarization and to external radiation.
Use two antenna oscillator horizontal positioned, realize high-gain horizontal polarization radiation effect by the one-to-two power splitter.Use two antenna oscillators vertically to place, realize the high-gain vertical polarized radiation effect by the one-to-two power splitter.Realize the dual polarization effect.
Utility is good, the stepped impedance of delicate structure changes main feeder and the subfeeder that the excessive one-to-two power splitter of joint connects antenna, has guaranteed good matching performance, has reduced the production debugging difficulty, has improved greatly production efficiency.
This WIFI directional bipolarization antenna is mainly used in residential quarter WIFI wireless Internet access frequency band signals and covers.This antenna be the dual polarization mode to external radiation, function admirable, cost is low, be easy to the debugging, matching effect is good, gain can reach 12dBi.
