Abstract

The utility discloses a double choking sleeve antenna composed of antenna unit, branch feed line, power divider, central copper tube and main feed line wherein the antenna unit consists of two conical vibrator connected through barum; the choking sleeve is disposed between the conical vibrator and central copper tube; branch feed line is disposed closely to outer wall of central copper tube. The double choking sleeve antenna of the utility has characteristics of good directional diagram, broad frequency band, arbitrary omnibearing array combination and block type design; metal wire can pass through center without influencing antenna performance.

Description

A kind of pair of chokes sleeve antenna

Technical field

The utility model belongs to the communication antenna technical field, especially relates to a kind of pair of chokes sleeve antenna.

Background technology

Development and use along with mobile communication, people are also increasing the quality that requires of mobile communication, if can't connect, perhaps the signal phenomenon that influences communication quality such as weak will be suffered a lot of complaints, and along with the increase of people to popular science knowledges such as microwave radiations, the user beats the also more and more stronger by the radiation worry of mobile phone at weak signal area, sets up more antennas exactly in order to solve above-mentioned phenomenon more, reach non-blind area and cover, and the covering level reaches-76dBm; But increase base station number simply is infeasible: first in some residential areas, and the installation of base station will be because of influencing the sub-district outward appearance or worrying that because of resident family radiation is rejected; The increase of second base station produces excessive fund input.Be widely used in the method for repeater, small-power driven antenna in recent years, and radiating antenna is used building, street lamp, syntype method embellished antennas such as ornament are accepted by vast owner, and embellished antenna has more and more been used.For still less destruction sub-district outward appearance with reduce construction cost, the all channel antenna of 806～2500MHZ can all communications of compatible present stage be used in the many uses of the antenna that sets up now, but mostly this all channel antenna is particularly omnidirectional antenna of low-gain antenna, and gain generally is no more than 6dB.

The embellished antenna that present stage uses is to use the antenna of indoor use in the past to cover the various methods making that beautify body more, the present domestic manufacturer production that also do not have of the embellished antenna of the high-gain of real omnidirectional, this antenna that market occurs above is to use the way of bundling antenna, final use of multiple antenna and road device carry out and the road, but because the spatial limitation mixer uses the lumped parameter design load power can not reach its nominal index, and the Insertion Loss of its introducing reached more than the 1dB, and this is that institute is unallowable.

Summary of the invention

The purpose of this utility model is to improve the deficiency of prior art and provides that a kind of directional diagram is good, bandwidth, can carry out two chokes sleeve antennas that any omnidirectional array combination, center can not influence antenna performance, building block type design by plain conductor.

The purpose of this utility model is to realize like this, a kind of pair of chokes sleeve antenna, form by antenna element, branch feeder line, power splitter, center copper pipe and main feeder that two taper oscillators connect into by Ba Lun, be characterized in being provided with the chokes sleeve at taper oscillator and center plumbers shed.

In order further to realize the purpose of this utility model, can be that described minute feeder line is close to center copper pipe outer wall setting.

Compared with the prior art the utility model has following distinguishing feature and good effect: this formula is provided with chokes sleeve with the center plumbers shed with novel employing in the taper oscillator that constitutes antenna element, effectively blocked the coupling of oscillator and center copper pipe, successful solution the matching problem of antenna; Divide feeder line to be close to center copper pipe outer wall setting, changed prior art, improved conformity of production dividing feeder line to walk in the inside of center copper pipe.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 is the cutaway view of Fig. 1.

Fig. 3 is an another kind of structural representation of the present utility model.

Fig. 4 is the cutaway view of Fig. 3.

Embodiment

Embodiment 1, a kind of pair of chokes sleeve antenna, with reference to Fig. 1, Fig. 2, it is the relative antenna element 8 that connects into by Ba Lun 2 of awl point by two taper oscillators 1, divide the two ends of feeder line 4 to connect respectively on the taper oscillator 1 in power splitter 5 and the antenna element 8, center copper pipe 6 passes the center of taper oscillator 1, main feeder 7 is connected with power splitter 5, be provided with chokes sleeve 3 at

taper oscillator

1 and 6 of center copper pipes, power splitter 5 determines that according to the number of antenna element 8 present embodiment adopts 8, two branch feeder lines 4 of two antenna elements to be connected with an antenna element 8 respectively, another termination two power splitters 5, this constitutes a kind of structure of the present utility model.

Embodiment 2, and a kind of pair of chokes sleeve antenna with reference to Fig. 3, Fig. 4, is on the basis of embodiment 1, divide feeder line 4 to be close to the 6 outer wall settings of center copper pipe, and other and embodiment 1 are identical.

The utility model operation principle is: two taper oscillators 1 have constituted common taper element antenna unit 8; realized basic aerial radiation; Ba Lun 2 carries out the imbalance-balance conversion of feed and the DC earthing that realizes is carried out lightning protected; the interference that can import power lead shielded power supply line in the center copper pipe 6; chokes sleeve 3 has been realized the coupling isolation of isolated antennas radiation and center copper pipe 6, has solved Broadband Matching and has made 3 frequency multiplication standing internal waves become possibility less than 1.5.

The solution of the wide band omnidirectional antenna success that the utility model is traditional relatively the center walk the existing problem of power supply to antenna interference, can be practical and embellished antenna more true to nature; Technology has relatively both at home and abroad realized not using the simple embodiment of mixer having reduced production cost.

Claims

1, a kind of pair of chokes sleeve antenna, form by antenna element (8), branch feeder line (4), power splitter (5), center copper pipe (6) and main feeder (7) that two taper oscillators (1) connect into by Ba Lun (2), it is characterized in that between taper oscillator (1) and center copper pipe (6), being provided with chokes sleeve (3).
