It is every using the non-transmission information of electromagnetic wave depending on engineering systems such as, radar, navigation, electronic countermeasure, remote sensing, radio astronomies, all according to
It is operated by antenna.With the popularization of air digital television signals, more and more people receive TV out of doors or in mobile
Signal, and it is not limited solely to interior.TV signal particularly is received in movement out of doors, because signal tower is fixed, and is connect
Receiving the position of antenna can constantly change, and TV signal also includes vertical polarization signal and horizontal polarization signals, it is therefore desirable to researches and develops
A kind of omnidirectional reception of double polarization antenna ensures preferable reception.
Utility model content
In order to solve the defects of prior art, this patent provides a kind of dual-polarization omnidirectional antenna, can be simultaneously to vertical pole
Change signal and horizontal polarization signals carry out omnirange reception, reception is good.
For above-mentioned technical problem, this patent so solves：A kind of dual-polarization omnidirectional antenna, including vertical polarization day
Line and circular horizontal poliarizing antenna；The vertical polarized antenna includes vertical fixed cover and cylindrical antenna, cylindrical antenna and fixes peace
In vertical fixed cover；The horizontally-polarized antenna includes horizontal fixed cover and coil antenna, coil antenna and is fixedly mounted on
In the fixed cover of level, vertical fixed cover is fixedly mounted on horizontal fixed cover.The cylindrical antenna receives vertical polarization signal, ring
Shape antenna receive horizontal polarization signals, while coil antenna can also realize horizontal polarization signals omnirange receive, ensure compared with
Good reception, and general wireless signal modulated by transmitting terminal after perpendicular signal and horizontal signal two in space
Kind different directions are propagated, and receiving terminal passes through vertical polarized antenna respectively and horizontally-polarized antenna receives.Vertical signal and horizontal letter
It is possible to change the direction of its signal number in space during propagating, is received which results in the signal of receiving terminal
Loss, while set vertical polarized antenna and horizontally-polarized antenna farthest to reduce the loss of the reception signal, because
Even if being changed for sense, the decomposition vector of its other direction can also be received by the antenna of other direction.
Further, the vertical polarized antenna is arranged on horizontally-polarized antenna center vertically upward direction, horizontal pole
Change the metal shielding board that antenna also includes being arranged between cylindrical antenna and coil antenna.The cylindrical antenna and coil antenna it
Between separated by metal shielding board, make it have higher polarization isolation, avoid two antennas from being interfered in reception signal.

The clutter that the horizontal reception antennas of VHF receive filters out, and the signal that the horizontal reception antenna of cylindrical antenna, UHF receives is filtered
After ripple, amplification, mixing output is carried out by blender, the 3rd wave filter can in mixed process caused clutter enter traveling one
The filtering of step, the signal after the 4th filters filter finally received again with the horizontal reception antennas of VHF carry out Hybrid amplifier
Output.
Further, the mixed filtering amplifying circuit also includes the LTE wave filters electrically connected with the 3rd amplifier.
Because antenna can more or less receive some mobile phone signals, therefore mixed filtering amplifying circuit in use
LTE wave filters are set in last output end, the interference of mobile phone signal are excluded, to obtain useful signal.
Further, the metal shielding board is circle, and its a diameter of 30 to 120mm.The diameter of metal shielding board is smaller,
The isolation effect that can be played is poorer, although and diameter is bigger can play preferable isolation effect, by volume is limited,
And setting excessive can also be received to signal to interfere, the metallic shield board diameter of above-mentioned setting makes gold in suitable scope
Category barricade can play preferably shielding isolation effect（The 50-80% interfered can effectively be reduced）While will not also account for
With excessive area and deamplification.
Further, the thickness of the metal shielding board is 0.1mm to 0.6mm.
Further, the metal shielding board is set in parallel on horizontally-polarized antenna center, with vertical polarization day
Line is vertical, apart from coil antenna 15mm to 35mm, apart from cylindrical antenna 5mm to 12mm.It can be seen that metal shielding board is from cylindricality
Antenna is nearer, and this patent is intended to receive the TV signal of horizontal polarization, suitable for the more region of horizontal polarization signals.
Further, the horizontal cross-section of the cylindrical antenna is cross, and the area increase of horizontal cross-section from top to bottom.
