To achieve these goals, technical solution adopted in the utility model is:
A kind of interior external hybrid antenna of full frequency band, comprise built-in aerial and external antenna, connected by a Switch Control circuit between built-in aerial and external antenna, described built-in aerial is FPC antenna, described external antenna is formed by a plain conductor coiled, and built-in aerial and external antenna are coaxial line, and feed end is provided with one piece of metallic plate, external antenna band support is 800Mhz ~ 2GHz, and built-in aerial band support is 800Mhz ~ 2GHz.
The beneficial effects of the utility model: compared with prior art, connected by a Switch Control circuit between built-in aerial of the present utility model and external antenna, make it possible to switch between built-in aerial and external antenna to affect the demands such as signal capture, network resident and complete wireless base station information collection, make more stable, the reliable and safety of work; External antenna band support of the present utility model is 800Mhz ~ 2GHz, and built-in aerial band support is 800Mhz ~ 2GHz, makes to support that external antenna and built-in aerial can use needs more.
Accompanying drawing explanation
Fig. 1 is the utility model circuit diagram.
Embodiment
Be described below as shown in Figure 1: a kind of interior external hybrid antenna of full frequency band, comprise built-in aerial and external antenna, connected by a Switch Control circuit between built-in aerial and external antenna, Switch Control circuit carries out switching controls by smart antenna software control algorithm, described built-in aerial is FPC antenna, described external antenna is formed by a plain conductor coiled, built-in aerial and external antenna are coaxial line, and feed end is provided with one piece of metallic plate, directivity for helical antenna depends on the diameter (D) of spiral and the ratio D/ λ of wavelength (λ) to a great extent, as D/ λ=0.25-0.46, antenna has greatest irradiation in the axial direction, and produce circularly polarised wave at axis direction, the pure row ripple that electric current on helical antenna is almost outwards propagated by distributing point, very little reflection is had at its end, thus the incident wave returning to floor is very faint, impact for floor can be ignored, spiral girth is about a wavelength, the current phase of the one relative both sides of circle is contrary, the circle of helix works for the electric current of corresponding point the effect of swinging to, thus the electric current often enclosing corresponding point place is in fact homophase, cause mutually strengthening along the axial far field of helix, described external antenna supports GSM/GPRS/EDGE/TD-SCDMA or GSM//GPRS/EDGE/WCDMA, wherein built-in aerial and external antenna all support that full frequency band transmits and receives, pulling out in external antenna situation, by the scheduling of smart antenna software control algorithm, built-in aerial can be switched in real time, do not affect signal capture, the demands such as network resident and complete wireless base station information collection, it is the core realizing hardware smart antenna that software algorithm controls, its function is basis signal environment, select certain criterion and algorithm, realize antenna calibration and control, channel allocation, power controls, multimode multi-frequency time-sharing multiplex etc., register in mobile collection device power-up, network selection, cell merge, under the agreement flow processs such as cell reselection, by the scheduling that software algorithm controls, in realizing, the real-time mixing of external antenna switches use, controlled by algorithm simultaneously, realize the time-sharing multiplex under multimode multi-frequency, the logic such as to reconnect, improve antenna gain and C/I index, decrease co-channel interference, external antenna band support is 800Mhz ~ 2GHz, built-in aerial band support is 800Mhz ~ 2GHz.The utility model forms hardware smart antenna and controls, similar diversity antenna array, points to and follows the tracks of source, wireless base station at any time, bringing very big improvement and the lifting of radio-frequency performance, comprise following function: the first, enhance receiving and transmitting signal intensity; The second, optimize noise effect, resist local interference; 3rd, reduce mobile device and base station transmitting power; 4th, decline and multipath effect optimization improve, and greatly improve the signal capture ability of handheld device under nlos environment; 5th, reduce because of the signal quality fall of blocking or distance increase causes.Simultaneously scheme of the present utility model is also for the mobile management of wireless device brings positive impact, comprising: controls of DCA, power, switching etc., and for multimodality equipment shortens handover success rate, less space interface signaling alternately, improves the utilance of system resource.
As shown in Figure 1, connected by a Switch Control circuit between built-in aerial of the present utility model and external antenna, select external antenna when the SW1 signal level of U9 is high, select built-in aerial when the SW2 signal level of U9 is high.
The performance parameters index of external antenna is as follows:
