Description

But wireless device with pullout antenna
Technical field
The present invention relates to have the wireless device of receiver and/transmitter circuitry and mechanical reconfigurable antenna, and relate to the correlation method that uses these equipment.
Background technology
Many inputs-many output (MIMO) emission modes are common characteristics of the wireless communication system of prior art.Particularly; They are basic to universal terrestrial radio electricity access (E-UTRA) (Long Term Evolution (LTE)), micro-wave access to global intercommunication (WiMAX) and the high-speed packet access (HSPA) of mobile communication standard evolution, and communicate by letter relevant with other application with wireless lan (wlan).The explanation of MIMO emission mode can be found in the people's such as Paulraj among the ISBN 0 521 82,615 2 " introduction of space-time radio communication (Introduction to space-time wireless communications) ".
In order to support the MIMO emission mode such as receive diversity (RD) and spatial reuse (SM); Portable terminal or radio modem must be equipped with at least two antennas that the dual-port antenna system is provided; And provide in the ordinary course of things and be designed to receive independently of one another (or emission, respectively) in the same frequency band from the multiport antenna of the signal of different port.For receiving mode, " independently " refers to that the different port of multiport antenna can receive the difference stack of importing multi-path component into, and this needs its polarization recombination radiation figure completely different.The measures of quantization of this ability is to propagate the relation between the signal that the different antennae port receives in the situation at given benchmark.
Usually the tolerance of using is to propagate the complex envelope coefficient correlation (CECC) between two aerial signals in the situation at isotropic Rayleigh.Owing to be applied to the reversibility pricinple of antenna, these statements are applicable to the emission mode operation similarly.
The key performance metrics that is used for the antenna of portable terminal or radio modem is its bandwidth under given desired operation frequency.From the reason of physics, other important tolerance (such as, radiation frequency) relevant consumingly with bandwidth (supposing to use good engineering practice).The bandwidth of antenna receives its size restrictions physically.If it is much littler than electromagnetic free space wavelength under the frequency of operation that the physical size of antenna becomes, then the bandwidth of antenna cube maximum sized with it roughly reduces pro rata.For the multiport antenna that is used for the MIMO emission, the minimum bandwidth of seeing in its arbitrary port will limit the MIMO operation.In the context of portable terminal and radio modem; Full-size be understood that the nominal antenna with it attached equipment (for example; Mobile phone or laptop devices) the full-size of assembled arrangement of conductive structure, current density can encourage (emission mode) or it to be coupled to its excitation (receiving mode) through importing electromagnetic wave into through antenna on this conductive structure.This coupling between antenna and the conductive soleplate all is absolutely necessary to the little mobile device of nearly all practicality.Its antenna otherwise required bandwidth will be provided.
The conductive soleplate of exploitation mobile device can be described to the excitation of the trait model of this base plate as the antenna extension.The radiation diagram of antenna-base plate combination is provided by the various characteristics pattern.For above-mentioned " independence " between a plurality of antenna ports in the MIMO antenna system that realizes portable terminal or null modem device coupling, the difference stack of trait model must encourage (emission mode) through the different antennas port.If this structure " greatly " (with the order of magnitude of half-wavelength) at least two sizes and if antenna element spaced apart along the periphery of conductive soleplate with the distance of enough " greatly ", then this relatively easy realization.
Unfortunately, this is not suitable for such as for example with the situation of the small size radio modem that blocks at a high speed form or realize with the form of USB (USB) adapter (dongle) that is attached to laptop devices (especially to be lower than the frequency of 1GHz).Then, the antenna in the modulator-demodulator is positioned at laptop devices single small size on one side.The result is, an antenna port illustrates wide bandwidth, and second or other ports less relatively bandwidth is shown.Particularly, it to become required instant bandwidth that the MIMO that is used for low frequency E-UTRA frequency band kind covers matchless in the physical size of card or USB rod at a high speed.
In order in these equipment, to realize effective multiport antenna system, the restriction that therefore surpasses card at a high speed or USB rod enlarge second or the volume of other antenna ports be enforceable.Unfortunately, this method causes huge equipment, and conflicts with the typical operating position (such as in train, using laptop devices) of consumer's expection and mobile device.
When the multiport antenna system in the mobile device mainly was designed for the frequency of operation of nearly 2GHz, this problem was not too serious in the past.Along with the frequency band in the scope from 698MHz to 960MHz is used to the MIMO emission, it becomes more serious problem now.In existing equipment (mainly be designed for RD and be not used in the SM pattern, and great majority are with higher frequency), follow the notion of elementary (good) and secondary (poor) antenna usually.But for the SM operation, all antennas should have suitable performance aspect bandwidth and the efficient.
, only individual antenna is integrated in the radio modem in other " MIMO " equipment at some, and the prediction aerial lug is used to attached secondary antenna.Supply to move the additional equipment of using because the user has to carry and assemble, so this solution must be considered to extremely inconvenient from user's viewpoint.This makes coupling difficult more.

In some examples of antenna, provide the N terminal port antennae to be used for the configuration that stretches, the some of them port is the part that when antenna is in the compressed configuration, does not re-use in mechanical stretchable K the port.Thus, in the difference configuration, there is the port of varying number, N port or N-K port.In some cases, antenna port is corresponding to antenna element, yet in other cases, the different port of multiport antenna maybe be unconnected with apart or the antenna element that can identify separately, and only be associated with the different radiation diagrams of entire antenna structure.Equally, the quantity of the antenna port quantity that can transmit greater than the difference in the mimo system of spatial reuse type.
Fig. 7,8 and 9 has the card embodiment of one pole and dipole
Some embodiments of the present invention relate to the radio modem that is equipped with multiaerial system, and this multiaerial system has at least two machine performances, and combination the automatic switchover suitable coupling and decoupling zero network between consistent with selected machine performance.The example of in the present embodiment, blocking at a high speed the removable module of form is provided with dual-antenna system.Antenna system can mechanically be switched between the compressive state of extended state that uses MIMO pattern (Fig. 8) and the non-MIMO pattern of use (Fig. 9).End view is shown in Fig. 7.This method basic principle behind is that non-MIMO pattern will be complete enough in quite a few of the mobile operating position with middle condition of acceptance.In fact, only there are two kinds of relevant situation of MIMO pattern wherein: wherein possible good condition of acceptance of SM and the poor reception condition that wherein RD is useful.
In end view, circuit board 120 is shown in the cross section, and is included in the shell 100.The moveable part of the antenna of fin 110 forms is at an end shown in the end view, and its length is shown in the plane graph.In end view, the circuit unit that constitutes match circuit is illustrated by parts MDN1 and MDN2 on the top of circuit board and bottom.
The situation of MIMO pattern is as shown in Figure 8 in the plane graph in this figure left side and shown in the end-view on this figure right side.Between two stretching fins 110, antenna system is with monopolar operation (with respect to the base plate of laptop devices) and dipole operative combination.In this stretched mechanical state, two fins of antenna are connected to first coupling and the decoupling zero network MDN1 (port one and 2) through the spring contact of printed circuit board (PCB) (PCB) top side.(one pole: common mode and dipole: differential mode) converting to can be in two actual separate signal of port 3 and 4 visits with two power modes for coupling and decoupling zero network.
Compact model is shown in Fig. 9.Two identical views are shown in Fig. 8.Two fins are pushed into shell to overlap each other, and wherein they keep connecting Face to face.The too little useful dipole modes that can not in this state, support low frequency of the size of this structure.Yet, still can use monopolar mode.The spring contact of PCB bottom side jointly is connected to two fins the port 5 of the second matching network MDN2.In this state, port 6 is individual antenna ports of coupling.
This structure can be equipped with spring between fin, thereby can carry out the switching from non-MIMO pattern to the MIMO pattern through the button of pushing retracting spring.To transmission or non-MIMO operation, can reuse thumb and forefinger and inwardly promote fin.
For the sake of clarity unshowned is port 3 and 4 to be broken off be connected, make on the contrary port 6 to be connected to the another switch of transceiver.This switch can activate through the same mechanical action that uses the sliding spring contact.Provide the example that Fig. 7 to 9 conduct illustrates notion.There is a large amount of optional realizations.Equally, can consider some realization characteristics, for example avoid interference near other connectors (according to the suitable orientation of fin slip).
This method has the direct summary to the N antenna system, and in the case, two power modes (common mode and differential mode) among Fig. 7 to 9 substitute with N eigen mode of antenna system.Basic point is that machine performance changes the electricity condition that is accompanied by coupling and decoupling zero network and changes.The aspect is more specifically, and the size of antenna system reduces automatically to cause the fact that the Maximum Rank of the wireless channel that can realize through antenna system reduces.
In plane graph, the size of the card in some examples is about 95mm and multiply by 35mm.In the configuration that stretches, width can extend to 70mm from 35mm.In principle, size is little on electricity with respect to the wavelength that uses.Stretch in the configuration the size such as width can up to quarter-wave, or can be up to a half-wavelength.The typical frequencies of operation can be 700MHz to 2.6GHz.In other cases, employed frequency can be low to moderate 400MHz or up to 3.5GHz.
Figure 10-12, other examples of reconfigurable antenna
Figure 10 to 12 illustrates other embodiment that antenna wherein has two dipoles that available different modes reconfigures.In Figure 10, compressed configuration is shown through the electrode couple on the substrate 70 (72,74) and (78,79).The match circuit 21 that is coupled to receiver and/or transmitter circuitry (not shown) is provided with at one end.One of dipole is hinged so that its orientation can change as illustrated in fig. 11.This illustrates hinge 80, and illustrate current in the configuration that stretches two orthogonally oriented dipoles.Figure 12 illustrates another optional stretching configuration.In the case, slide block 90 is provided.This slide block can increase the interval between the dipole under the situation that does not change orientation.Itself and Figure 11 combination are to change at interval and the change orientation.In some instances, can have plural dipole, each dipole has different orientations or interval.
In principle, compressed configuration only can be used for down link, and when the needs up link, uses the configuration that stretches, or vice versa.
Generally speaking; Below described wireless device, this wireless device is included in the same frequency band supports at least two the independently receiver circuit (23) of transmission path and/or the multiport antennas (20) with N port (22) of transmitter circuitry and available receiver or transmitter circuitry simultaneously.The multiport antenna has compressor mechanical state and stretched mechanical state, and is connected to N port of receiver and/or transmitter circuitry (23) via 2N port match and decoupling zero network (21).This 2N port match and decoupling zero network have a plurality of optional electricity conditions, and each electricity condition is corresponding in the machine performance at least one.It is the operation in the wireless channel of N in order that machine performance and electricity condition a kind of makes up permission.Second combination of machine performance and electricity condition allows in order less than the operation in the wireless channel of N.When the user can't use pullout antenna, can under the situation of the convenience that maintains sex-limited ability, obtain better MIMO performance with pullout antenna configuration.
