Abstract
The invention discloses a kind of active antenna, comprise outer cover and inner antenna oscillator, activated amplifier and antenna-reflected plate thereof, described activated amplifier is made up of structure cassette holder, amplifier veneer and structure lid, within described amplifier veneer is placed in structure cassette holder and structure lid, the base plate of described structure cassette holder connects with antenna oscillator as antenna-reflected plate. Active antenna of the present invention, the base plate that the structure of activated amplifier unit is closed to seat is directly as antenna-reflected plate, replace original antenna-reflected plate to close with structure the version that a split is connected, antenna-reflected plate and activated amplifier structure box seat grounding shell are combined together, and earthing effect is better; Owing to having reduced independent antenna-reflected plate, just make the height dimension of whole active antenna less, thereby alleviated the weight of whole active antenna simultaneously, reduced the cost of active antenna.
Description
Technical field
The present invention relates to a kind of antenna structure, especially a kind of structure of active antenna.
Background technology
Antenna is as the carrier with reception signal to external radiation, and the quality of its performance directly affects the efficiency of communication system and the Stability and dependability of signal transmission, in the time of designing antenna, more wishes more miniaturization of antenna under identical index.
Along with mechanics of communication development, active antenna is more and more in the application of field of mobile communication. Active antenna will transmit and receive real reach, solve equal area coverage, and active antenna does not need very high-power, and receiving sensitivity is high, and active antenna progressively becomes a kind of main flow antenna form that wireless signal high-quality covers like this.
Existing active ceiling mount antenna, it forms by outer cover and inner activated amplifier unit, antenna oscillator and antenna-reflected plate form, wherein activated amplifier unit is by structure cassette holder, amplifier veneer and structure lid form, structure cassette holder, structure lid is Al-alloy parts, there is good conduction and shielding properties, the inner amplifier veneer of placing, play ground connection effect simultaneously, antenna is in the time of debugging and production, debug respectively behind antenna and activated amplifier unit, again activated amplifier unit is fixed on antenna-reflected plate with securing member, make antenna-reflected plate form ground connection, it is good that split between its amplifier unit of this antenna and antenna-reflected plate connects the loose contact that can cause between the two, affect on the one hand earthing effect, be unfavorable for reducing of antenna volume, may cause on the other hand the inconsistent of directional diagram that active antenna transmitting covers and original passive antenna, produce pattern distortion.
Summary of the invention
The object of the present invention is to provide a kind of active antenna, the base plate that the structure of activated amplifier unit is closed to seat, directly as antenna-reflected plate, replaces original antenna-reflected plate to close with structure the version that a split is connected, and can effectively address the above problem.
For reaching this object, the present invention by the following technical solutions:
A kind of active antenna, comprise outer cover and inner antenna oscillator, activated amplifier and antenna-reflected plate thereof, described activated amplifier is made up of structure cassette holder, amplifier veneer and structure lid, within described amplifier veneer is placed in structure cassette holder and structure lid, the base plate of described structure cassette holder connects with antenna oscillator as antenna-reflected plate.
Further, described structure cassette holder, structure lid structure are Al-alloy parts, and both connect by securing member.
Preferably, described antenna oscillator is two centrum oscillators, for aluminum alloy materials is made, adopts securing member to connect with antenna-reflected plate.
Especially, described outer cover is made up of the upper outer cover snapping together and lower outer cover, and both connect by securing member.
Especially, described outer cover is made of plastics.
Active antenna of the present invention, the base plate that the structure of activated amplifier unit is closed to seat is directly as antenna-reflected plate, replace original antenna-reflected plate to close with structure the version that a split is connected, antenna-reflected plate and activated amplifier structure box seat grounding shell are combined together, and earthing effect is better; Owing to having reduced independent antenna-reflected plate, just make the height dimension of whole active antenna less, thereby alleviated the weight of whole active antenna simultaneously, reduced the cost of active antenna.

Wherein: 1, upper outer cover; 2, lower outer cover; 3, antenna oscillator; 4, structure cassette holder; 5, base plate; 6, structure lid; 7, amplifier veneer.
Detailed description of the invention
Fig. 1 to 3 has provided a specific embodiment of active antenna of the present invention, its formation comprises the outer cover that outside is made of plastics, being covered with outer cover 1 and lower outer cover 2 fastens and forms, and form sealing connection by securing member, antenna oscillator 3 and activated amplifier are installed therein, described activated amplifier is made up of structure cassette holder 4, amplifier veneer 7 and structure lid 6, within described amplifier veneer 7 is placed in structure cassette holder 4 and structure lid 6, the base plate 5 of described structure cassette holder 4 connects with antenna oscillator 3 as antenna-reflected plate.
Structure cassette holder 4 and structure lid 6 structures are Al-alloy parts, have good conduction and shielding properties, and both connect by securing member. Antenna oscillator 3 is two centrum oscillators, for aluminum alloy materials is made, adopts securing member to connect with the antenna-reflected plate that the base plate 5 of structure cassette holder 4 forms, and can obtain better earthing effect; The structure of this active antenna is integrally formed antenna-reflected plate and structure cassette holder, has reduced independent antenna-reflected plate, makes the height dimension of whole active antenna less, thereby has alleviated the weight of whole active antenna, has reduced the cost of active antenna.
Know-why of the present invention has below been described in conjunction with specific embodiments; these are described just in order to explain principle of the present invention; and can not be interpreted as by any way limiting the scope of the invention; based on explanation herein; those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present invention, within these modes all will fall into protection scope of the present invention.
