Embodiment

In Fig. 1, label 1 refers to for example can be arranged on the circuit card in honeycomb or the mobile phone.Circuit card 1 comprises carrier 2 and superincumbent at least at least one metal backing 3 of at least one dielectric material.But circuit card also can comprise a plurality of conductive layers and the insert layer that is arranged on a plurality of dielectric materials therebetween, thin slice or layer corresponding to metal backing 3.On circuit card 1, the radiator of optional type is set.In illustrated embodiment, show the quarter-wave slot radiator with mode for example.The implementation method of radiator or slot 4 is that metal backing 3 is removed from the two sides of carrier 2, and making slot is transparent with respect to radiation.Can understand that from figure slot 4 is porose 5, as mentioned above, its requires it is tuned as at quarter-wave resonance.Radiator also can be a half-wave element, and in having the example of slot radiator, it requires slot long and without any the part similar to hole 5; So as half-wave element, slot is closed.Also can consider the radiator of other type.

For power to radiator (promptly powering to quarter-wave slot 4 in above-mentioned example), utilization will be at the electric supply installation 6 of following detailed description.Electric supply installation 6 can be mounted in the independent unit that certain distance is arranged apart from radiator 4, also can whole or partly be attached in the circuit card 1.Be not electrically connected between electric supply installation 6 and the radiator 4.

A more than if desired radiator (this is possible according to the present invention) then can be arranged on a more than radiator on the same ground plane, that is, and and in same metal backing 3.In using the example of slot radiator, physically adjacent to each other even two slots are arranged in, they can not have film to ring mutually yet.So, by adopting a more than slot, might realize multiband antenna according to the present invention, wherein each wave band all has big bandwidth.

The orientation of the different modes by slot for example, by with they vertically be arranged to each other in the right angle, also can influence radiation diagram, makes the radiation lobe difference of two radiators.For example, vertically approach level if a slot is arranged to it, its radiation lobe then can be vertical orientated, and this is a main advantages in the GPS device.In like manner, slot have vertical vertically, its radiation lobe is level basically.

Metal backing 3 also can be arranged on the casing of mobile phone, not only can be at medial support casing but also can be in outside decoration cabinet.In above-mentioned example with slot radiator, this point also is suitable for, and promptly also is arranged on the casing.

In the example of Fig. 1, utilize quarter-wave slot radiator 4, radiator and electric supply installation 6 or exciter have longitudinal direction separately, and these longitudinal directions are parallel to each other.But,, also can make these longitudinal directions angled mutually in order to set or to finely tune.Correspondingly, be same purpose, also can change the distance between radiator 4 and the exciter 6.If the design of radiator is different from the slot 4 shown in the above demonstration, this point also is suitable for.

Fig. 3 illustrates according to antenna assembly of the present invention with the simplified schematic diagram form.Described antenna assembly is identical in function aspects and antenna assembly shown in Figure 1, and just orientation is different.

Fig. 3 illustrates ground plane 3, and it can be by the formations such as metal level, metal forming of (for example metallized area of circuit card or mobile phone casing) on the suitable carrier of insulation non-magnetic material.Similar with the embodiment of Fig. 1, in ground plane 3, be provided with slot 7, it has openend 8.Slot can be tuned at quarter-wave resonance, wherein the length of slot has determined relevant wavelength.

Even physical size is bigger, the present invention also has the possibility of half-wave resonator, and in this case, slot 7 is closed than length and two ends in this implements.

Among Fig. 3, slot 7 is by 6 power supplies of exciter or electric supply installation, electric supply installation 6 comprise first or center conductor 9, the first conductors 9 have first end 10 and second end 11.In the embodiment of reality, first conductor 9 can be made of the part of the center conductor of coaxial cable 12, and the other end (not shown) of coaxial cable is connected to the circuit of the mobile phone that comprises antenna assembly.

Electric supply installation 6 comprises that also second conductor, 13, the second conductors 13 have first end 14 and second end 15.First end 14 of second conductor 13 is connected to screen or the earthing conductor 16 in the coaxial cable 12, and second end, 15 terminates.Second conductor 13 also can be connected to ground plane 3, and in this plane with its first end, 14 ground connection.First end 14 of second conductor 13 also can be connected to ground by other conductor (rather than screen 16 of coaxial circuit 12).

In illustrated embodiment, therefore the physical form of second conductor 13 alternately is being positioned on the not ipsilateral of first conductor 9 along its some zones at least a portion of its longitudinal length twist.So the described helix or second conductor 13 surround around first conductor 9 or extend three-dimensionally.This also is applicable to the embodiment of the following modification that will describe.Helix can be shorter than, equal (Fig. 3) or be longer than second conductor.

First conductor 9 be positioned at slot 7 vertically on, in ground plane 3 or in parallel.Between first and second conductors 9 and 13, do not electrically contact, do not electrically contact between the metal in second conductor 13 and ground plane 3 yet, except first end, 14 ground connection second conductor.Distance between first conductor 9 and the ground plane (unless first conductor is arranged in ground plane) has determined the connection degree between first conductor 9 and the slot 7.

Second conductor 13 forms the inductance that distributes along first conductor, 9 longitudinal lengths.And second conductor 13 forms the electric capacity between himself and first conductor 9, and described electric capacity is also along the distribution of lengths of first conductor 9.In addition, in second conductor, between tight each adjacent circle electric capacity is arranged also.

In the antenna assembly according to Fig. 3, the length of slot 7 has determined the center of the resonance range of antenna assembly work.The length and the slit length of the center conductor or first conductor 9 are adaptive.But the length of first conductor 9 is not crucial especially, as long as it enough can hold the required number of turn of second conductor greatly.

Utilize the design shown in Fig. 3, antenna assembly just can have the wideband resonance scope, shown in arrow A among Fig. 2.

In the position of switch shown in Figure 8 51, first end 14 of second conductor 13 is by electric capacity 50 ground connection shown in the top among the figure.But in other position of switch 51, partial inductance 43 is connected between one of first end 14, electric capacity 50 and the ground.

In the embodiment of Fig. 9, first end 14 as the above-mentioned end that is connected to inductance 43 of second conductor 13, the other end of inductance 43 is connected to ground 42.The upper end of inductance is connected on a plurality of electric capacity 53 that vary in size by branch conductors 52.The other end of these electric capacity is connected to switch 54, utilizes this switch any optional electric capacity can be connected to ground.

The embodiment of Fig. 9 can be called classification adjustable variation embodiment illustrated in fig. 7.

Perhaps, can design switch 54 like this, make its a plurality of electric capacity 53 in parallel and they ground connection.
