Description
Technical field
The present embodiments relate to field of communication devices, particularly relate to a kind of antenna-switching device.
Background technology
At present, mobile phone just towards multi-functional, miniaturization, Low emissivity loss direction develop, antenna for mobile phone receive electromagnetic performance directly determine cellular radiation receive electromagnetic wave signal performance, affect the ability to communicate of mobile phone.
Owing to signal can be decayed in communication process, so generally adopt diversity technique when mobile phones design, improve the correct decision rate of signal, resist the harmful effect that signal fadeout causes.Mobile phone arranges main collection antenna and diversity antenna.Main collection antenna, is responsible for transmission and the reception of radiofrequency signal；Diversity antenna, is only responsible for receiving signal and not sending, and receiver can merge process the signal received from two interfaces, thus obtaining diversity gain.Considering the not same-action of main collection antenna and diversity antenna, the two is often arranged on different positions, and distant.
Under the current stacking scheme of mobile phone; DPDT (DoublePoleDoubleThrow would generally be used; DPDT) working method that switchs realizes under certain conditions; make the power and energy of main collection antenna and diversity antenna; in order to ensure mobile phone transmission power, DPDT switch is generally placed upon on main antenna radio signal transmission path.Main collection antenna and diversity antenna relative distance in position are farther out, so diversity antenna needs to use two holding wires to be connected to realize diversity antenna with DPDT switch, DPDT switch is connected with diversity switch, owing to diversity antenna and DPDT exist electric potential difference between switching, such signal just creates the Insertion Loss of two signal line through two signal line.When antenna is direct-connected, diversity signal needs how just to enter diversity switch through two signal line, so can add receiver front end Insertion Loss, cause reducing mobile phone receiving signal sensitivity.
Fig. 1 is that tradition uses the antenna straight line of DPDT switch to connect the schematic diagram of working method.Fig. 2 is the schematic diagram that tradition uses the antenna interconnection working method of DPDT switch.As depicted in figs. 1 and 2, under the current stacking scheme of mobile phone, when being directly connected to work or interconnection work at antenna, in order to ensure mobile phone transmission power, being typically on the radio signal transmission path of main collection antenna and arrange a DPDT switch, now main collection antenna and diversity antenna share a DPDT switch.
Fig. 3 is the schematic diagram of the working method not using DPDT to switch.As it is shown on figure 3, under this working method, the transmission path of radiofrequency signal is not provided with DPDT switch.Fig. 3 and Fig. 1, working method shown in Fig. 2 is compared, it can be seen that use the antenna of DPDT switch to connect under working method in tradition, particularly in antenna straight line connect working method time, main collection signal enters into main collection switch either directly through DPDT switch, and diversity signal needs to be transferred to DPDT switch from the diversity antenna of mobile phone through a signal line, then it is transferred to diversity switch then through a signal line, so will cause that diversity signal to additionally go through two holding wires, such cabling can cause that receiver front end Insertion Loss increases, radiation efficiency reduces, cause that antenna for mobile phone receiving signal sensitivity declines, affect user's experience when using mobile phone.
To sum up, it is big to there is receiver front end Insertion Loss in prior art, the problem that radiation efficiency reduces.Therefore, it is necessary to the technological means proposing to improve solves the problems referred to above.
Summary of the invention
For prior art Problems existing, the embodiment of the present invention provides a kind of antenna-switching device, it is possible to achieve on existing antenna foundation, reduces antenna for mobile phone front end Insertion Loss, improves the performance of antenna for mobile phone, improves antenna for mobile phone sensitivity.
The embodiment of the present invention provides a kind of antenna-switching device, for the path being made up of two front end antennas and two back end link, wherein, described front end antenna includes diversity antenna and main collection antenna, described back end link includes point link and primary link, and described antenna-switching device includes:
