For example, the resonant element of antenna can be formed around rear wall periphery is mounted on.In a suitably-arranged, induction part
104 coils, which are set to, to be contacted with 105 rear wall of bottom to receive wireless charging signal by dielectric rear wall.In this case, day
The resonant element of line can surround the electromagnetic induction coil at rear wall inner surface.In this way, antenna element is formed by neighbouring rear wall, if
Standby vertical height is than transmitting-receiving efficiency base shorter and antenna in the case where antenna resonating element is located at equipment elsewhere
This is constant.The inactive region of operation portion 121 can also be reduced by forming antenna along the rear side of equipment, because antenna can pass through equipment
Rear side emits radiofrequency signal without worrying that signal stops the operation module in operated unit 121.
Highest is presented in the space between separable components and pedestal in the electric field amplitude generated by antenna.Signal can be along
The surface of resonant element and pedestal far from separable components outwardly direction to propagate, so that being properly received by external communication device
Wireless signal, even if antenna is close to pedestal and is typically remote from external communication device direction.In fact, pedestal can be used for opposite pedestal
There is no the case where enhance electromagnetic wave propagation.For example, in the case where pedestal is not present, it can by the radiofrequency signal that antenna emits
It can be interfered.However, signal suitably can be guided to improve communication efficiency in the presence of pedestal.
But this design sometimes may generate impedance discontinuity between antenna and wireless communication module.Impedance discontinuity energy
Cause boundary of some RF energies between antenna and the peripheral parts of wireless communication module be reflected rather than for it is outer
Portion's equipment conveys signal.If these reflections are not compensated for, antenna may variation over time and it is detuning, to reduce
Overall antenna efficiency and communication quality during equipment normal operating.In order to compensate for these antenna impedance variations, 102 quilt of control panel
It is configured to the impedance matching module that control is couple to antenna, to ensure that the peripheral parts of antenna and induction part match but regardless of day
How line is loaded by rear wall.Sometimes, other than increasing adjustable impedance matching module, control panel 102 can be adjustable in adjusting
Humorous component is detuning to cover wider communication band and compensate antenna caused by the interference as exterior object to antenna.Control panel
102 can be used any desired information to determine when and how to adjust adjustable impedance matching module and compensate antenna
Change.For example, control panel 102 can adjust impedance matching module based on the instruction received from external wireless access point (WAP).
Alternatively, control panel 102 can current operation status based on equipment adjust the impedance matching module.For example, control panel 102 can be known
Other usage scenario (for example, whether separable components are used for browsing content, progress call, reception voice messaging etc.) is with true
It is fixed how to adjust the impedance matching module.As another example, control panel 102 may be identified for identifying how to adjust the impedance
With module such as optical sensor, proximity sensor, touch sensor, indicate data of the user close to rear wall.As again
One example, control panel 102 collect the characterization signal for how adjusting the antenna performance of impedance matching module for identification.Have
When, the statistical value of user's habits information about equipment can be also handled, adjusts the impedance matching circuit to determine how.
Control panel 102 may include baseband processing module, memory module and for control wireless communication module transmitting and/or
Receive the control circuit of radiofrequency signal.When in use, the digital data signal of electric accessories equipment transmitting can be by one or more
Baseband processor generates.Baseband processor come modulated digital signal and can provide corresponding output letter according to default communication protocol
Number for being emitted to radio-frequency receiving-transmitting portion.In an example, radio-frequency receiving-transmitting portion 103 may also include frequency mixer, and output signal is turned
Change to radio frequency and by emission of radio frequency signals to radio frequency power amplification modules.Sometimes, radio-frequency receiving-transmitting portion 103 may include converting output signal
For the A/D converter of corresponding analog signal.Control panel 102 is also configured to adjust the biased electrical for being supplied to radio frequency power amplification modules
Pressure.Bias voltage can be used as the supply voltage of one or more active power amplifier stages in radio frequency power amplification modules.Wireless
Between data transfer period, the output power for emitting signal can be amplified to sufficiently high level to ensure to believe enough by radio frequency power amplification modules
Number emissive porwer.
The output of radio frequency power amplification modules can be coupled to radio-frequency front-end by RF coupler.Front end may include adjustable pair net
Adjustable impedance matching module of network.Impedance matching module may include passive and/or active adjusting part, such as resistance,
The composition RLC network of inductor and capacitor, between such peripheral parts of the adjusting for ensuring antenna and radio frequency power amplification modules
Impedance matching.Control panel 102 can supply control signals to adjustable impedance matching module in front end.
In some cases, control panel 102 controls the impedance matching module so that specific predetermined matching resistance is presented
Anti-, which is based only upon depending on the frequency of signal to be conveyed on antenna.For example, control panel 102 can be stored for matching mould
The initialization of calibration data of block, for identification specific setting corresponding to the impedance matching module of each possible operating frequency.
When 102 determination of control panel will be used for wireless communication frequency, impedance matching module is placed in be identified by initialization of calibration data
In corresponding setting.
Control panel 102 can be emitted by way of rear wall based on antenna, execute the dynamic to the impedance matching module in real time
It adjusts.For example, can start antenna element when pedestal is close to antenna and match the impedance of antenna no longer with equipment 4.Control panel
102 can control the impedance of adjustable impedance matching network to match the antenna starting triggered by pedestal.When impedance matching net
It is detuning caused by can reduce due to antenna load variation when network and antenna match, and antenna efficiency can be made to maximize.As another
Different impedance matchings is presented when equipment is oriented with respect to pedestal in one example.
The impedance phase and amplitude of antenna can be used to determine whether the operation of antenna has been subjected to the running environment of equipment
Influence, such as whether exterior object made the load of antenna detuning or changed.Control panel 102 can detect collected phase and
The variation of amplitude information is to identify when detuning by the interference of exterior object antenna is/load.If control panel 102 detects day
It is detuning to compensate this to adjust impedance matching network that control signal can be transmitted since antenna is detuning in line.
The present invention is not limited only to above-described embodiment, but in the range of the present inventive concept being determined by the claims that follow
It can be there are many modification.In the range of present inventive concept, the attribute of different embodiments and application can be with another embodiment
Or the attribute of application is used in combination.
