The top omnidirectional antenna is inhaled in a kind of dual polarization

Technical field

The utility model belongs to the communication antenna technical field, especially relates to a kind of dual polarization and inhales the top omnidirectional antenna.

Background technology

Development and use along with mobile communication; 3G network is popularized, and the practicality that the 3G data service brings highlights, and is not enough but 3G data service networking speed has seemed; The 4G network also begins to get into the trial period thus; Because the relevant parameters such as communication speed of 4G network are had relatively high expectations,, can't satisfy the needs of 4G network communication owing to have the structural limitations of communication antenna now.

Summary of the invention

The purpose of the utility model is to improve the deficiency of prior art and provides a kind of characteristics to the 4G network to realize that at indoor distributed system the signal dual polarization that covers the signal dual polarization, realizes the 4G network covers, can offer the base station better signal quality and inhales the top omnidirectional antenna with the dual polarization of using higher data rate.

The purpose of the utility model is to realize like this; The top omnidirectional antenna is inhaled in a kind of dual polarization; Form by full-wave dipole, taper oscillator and base plate, be characterized in that two full-wave dipoles circularize to be fixed on the taper oscillator that the taper oscillator connects base plate and ground connection through short-circuit line; The taper oscillator links to each other with the perpendicular polarization feeder line bottom and accomplishes feed; Two full-wave dipoles are connected with middle Ba Lun through 1 impedance conversion line respectively, the wherein impedance conversion line and the Ba Lun interconnection on one side, and the output horizontal polarization feeder line of Ba Lun passes the taper oscillator and base plate is drawn out to antenna.

In order further to realize the purpose of the utility model, can be that the output horizontal polarization feeder line of Ba Lun passes the taper oscillator from the taper oscillator is installed the hole of short-circuit line position, and pass base plate along short-circuit line and be drawn out to the antenna outside.

In order further to realize the purpose of the utility model, can be that described short-circuit line is evenly to distribute more than two and at interval.

Compared with present technology the utility model has following distinguishing feature and good effect: the utility model adopts 2 full-wave dipoles to circularize and is distributed in the radiation of horizontal plane completion horizontal polarization; Ring type vibrator is fixed on above the taper oscillator; The taper oscillator is connected ground connection and accomplishes the supporting role to the taper oscillator simultaneously through short-circuit line with base plate; The taper oscillator links to each other with the perpendicular polarization feeder line bottom and accomplishes feed; Ba Lun in the middle of 2 full-wave dipoles are connected in through 2 impedance conversion lines; Interconnection when wherein being connected with Ba Lun on one side, the output horizontal polarization feeder line of Ba Lun passes the taper oscillator from the taper oscillator is installed the hole of short-circuit line position, and passes base plate along short-circuit line and be drawn out to that antenna is outside accomplishes output.

The utility model perpendicular polarization signal connects the taper oscillator after being imported by the perpendicular polarization feeder line, and the shape oscillator adopts the broadband design and increases by 3 short-circuit lines and can make work bandwidth reach 3 frequencys multiplication, promptly more than the 806-2500MHZ; The horizontal polarization signal is accomplished uneven balance-conversion through Ba Lun after being imported by the horizontal polarization feeder line; Ba Lun adopts compensation Ba Lun to have the good characteristics of bandwidth symmetry; Ba Lun imports through the impedance conversion line a full-wave dipole feed; Another full-wave dipole connects Ba Lun after intersecting through the impedance conversion line; Let the signal phase of 2 full-wave dipoles differ 180 degree, omnidirectional radiation must carry out interconnection here so that its 2 oscillator phase phasic difference 180 is spent in order to produce, otherwise will produce axial radiation.

The utility model is novel to provide a kind of omnidirectional radiation dual polarized antenna, its perpendicular polarization 806-2500MHZ, and horizontal polarization 1900-2200MHZ mainly is used in field of mobile communication (4G) signal and covers, and has bandwidth, 3G, 4G and uses frequency range dual polarization characteristic; The volume I is to be designed to the ceiling light form; The main 3G of application, 4G network indoor signal cover, and particularly 4G uses and can realize polarization diversity, improve signal quality and 4G data rate, and support the indoor signal of 2G, 3G frequency range to cover compatible 3G network simultaneously.
