Description
Technical field
The utility model relates to a kind of directional antenna, particularly relates to a kind of gain directional antenna that can improve gain.
Background technology
At present, known small size 2.4G directional antenna all is the antenna that adopts the rhombus oscillator, and its gain is also not high, and effect is also good inadequately.And the parabolic directional antenna that gain can be done very highly, but its volume very huge (directly not waiting to several meters through 300mm) can not be used on the indoor wireless equipment easily.Secondly, present indoor directional antenna does not all have the function of regulating the polarization angle.The 2.4G directional antenna that existing market can be seen, the big volume that gains are just big, install and use inconvenience, and the gain that volume is little is lower again, and can easily not regulate polarised direction.
Summary of the invention
The purpose of this utility model provides a kind of gain directional antenna simple, that volume is little, gain is high, easy to adjust of making.
The purpose of this utility model realizes by following technical proposal: gain directional antenna, comprise oscillator, reflecting plate, connection oscillator and reflecting plate connecting rod, be connected the shielding conductor on the oscillator, wherein connecting rod is fixedlyed connected by a jockey with reflecting plate, be connected with a support on the reflecting plate, oscillator is a rectangular configuration, and the mid point on two long limits in rectangular configuration respectively has an outstanding structure towards the rectangular configuration central point, and design has distributing point on this outstanding structure.
Oscillator is that the length of side is the rectangular configuration of 32mm ± 0.1mm*64mm ± 0.1mm.
Jockey is a hollow-core construction, and shielding conductor passes from the hollow part of this jockey.
Shielding conductor is connected the distributing point position.
Connecting rod is connected any one distributing point position.
Signal reception process of the present utility model is:
1, when signal be electric field, field intensity for from the top down the time, two minor faces that the signal of reception is equivalent to the rectangular configuration of oscillator add two the outstanding structures in center signal phasor and, at this moment be effective reception.
2, when signal be electric field, field intensity is (because of symmetry, right-to-left is in like manner) from left to right because left and right directions can't form the loop, so the electric field signal of left and right directions is not received, thereby reach the effect of this direction interference signal of shielding.
3, when come from the oscillator opposite be field signal the time, because the centre wavelength of 2.4G signal is 12.2mm, rectangle is divided into 2 squares by the line segment of centre so, be equivalent to the loop aerial of 2 1/4 wavelength this moment, receive two rings the magnetic induction signal vector and, and the signal that comes from the back side, the plate resistance that is reflected retaining just reaches the purpose that shields back side signal.
4, when from oscillator up and down, promptly side direction is come when being field signal, and the non-inductive area of this direction reaches the purpose of shielding.
From architectural feature of the present utility model as can be seen, oscillator and reflecting plate relative fixed, SMA or other interfaces are done in the support below, become practical antenna.And reflecting plate and support are to flexibly connect, 90 degree can be done clockwise or be rotated counterclockwise to reflecting plate and oscillator together in vertical direction, thereby the adjustable range of totally 180 degree can be arranged, can regulate receiving the polarization angle easily, can receive any polarized wave of perpendicular polarization to horizontal polarization.The utility model can be connected on indoor route, the network interface card easily, strengthens directional transmissions, receiving ability, improves the wireless connections effect.
Architectural feature to sum up of the present utility model as can be seen, advantage of the present utility model is: make simple, volume is little, gain is high, easy to adjust.
