The reserved location in space is not limited to above-mentioned several kinds of forms on the said antenna 100, as long as the space is arranged on the dual polarized antenna.For example, the space can also be arranged on the medium substrate.
Said electronic component of the present invention is perceptual electronic component, capacitive electronic component or resistance.After in the headspace of antenna, adding this type of electronic component, can improve the various performances of antenna.And, can realize the adjustable of antenna performance parameters through adding the electronic component of different parameters.Adding electronic component in the space can have following several kinds of situations because the b face of medium substrate is identical with a face, so following do explanation with a face:
(1) in the space of first feeder line, second feeder line, adds perceptual electronic component; Using formula:
can know square being inversely proportional to of size and operating frequency of inductance value; So, can realize through suitable embedding inductance or perceptual electronic component when the operating frequency that needs is when hanging down operating frequency.The inductance value range of the perceptual electronic component that adds is preferably between the 0-5uH, because, thereby if the too big alternating signal of inductance value will be had influence on the radiation efficiency of antenna by perceptual electronic component consumption.Certainly also possibly in the space on first feeder line, second feeder line, add resistance to improve the radiation resistance of antenna.Certainly, also a plurality of spaces can be set on first feeder line and second feeder line, segment space embedded resistor wherein, segment space embeds perceptual electronic component, has both realized the adjusting of operating frequency, can improve the radiation resistance of antenna again.Certainly according to other needs, also can only in segment space, add electronic component, the lead short circuit is used in other space.
(2) embed the capacitive electronic component in the space between first feeder line 2 and first sheet metal 4, between second feeder line 3 and first sheet metal 4.Here regulate first feeder line 2, second feeder line 3 and be coupled through embedding the capacitive electronic component with signal between first sheet metal 4; Using formula:
can know square being inversely proportional to of size and operating frequency of capacitance; So when the operating frequency that needs is when hanging down operating frequency, can realize through suitable embedding capacitive electronic component.The capacitance scope of the capacitive electronic component that adds is usually between 0-2pF, but the capacitance that embeds along with the variation of operating frequency of antenna also possibly exceed the scope of 0-2pF.Certainly, also can be between first feeder line 2, second feeder line 3 and first sheet metal 4 preset a plurality of spaces, in not being connected with the space of electronic component, adopt the lead short circuit.
(3) the perceptual electronic component of embedding and/or resistance are arranged in the space 6 on first metal routing 43 of first sheet metal.The purpose that embeds perceptual electronic component here is the inductance value that increases by the first sheet metal internal resonance structure, thus the effect that the resonance frequency and the bandwidth of operation of antenna played adjusting; The purpose of embedded resistor is to improve the radiation resistance of antenna here.So, then decide as required to embedding perceptual electronic component or resistance.In not embedding the space of electronic component, adopt the lead short circuit in addition.
(4) embed the capacitive electronic component in the space of on first micro groove structure 41 and second micro groove structure 42, reserving 6.Embedding capacitive electronic component can change the resonance performance of first sheet metal, the Q value and the resonance working point of finally improving antenna.As common practise, we know that the relation of passband BW and resonance frequency wo and quality factor q is: BW=wo/Q, and this formula shows that Q more greatly then passband is narrow more, the more little then passband of Q is wide more.Other has: Q=wL/R=1/wRC, and wherein, Q is a quality factor; Supply frequency when w is circuit resonance; L is an inductance; R is the resistance of string; C is an electric capacity, can be known by the Q=wL/R=1/wRC formula, and Q and C are inverse ratio, therefore, can reduce the Q value through adding the capacitive electronic component, and passband is broadened.
Dual polarized antenna of the present invention can be the same structure before not adding any element; Just through adding different electronic components at diverse location; And the difference of the parameter of electronic component (inductance value, resistance value, capacitance); Realize the performance parameter of different antennae, promptly realized versatility, therefore can significantly reduce production costs.
Said space of the present invention can be a pad, also can be a vacancy.Pad configuration can be referring to the pad on the common circuit board.Certainly, the needs that the design consideration of its size is different can be different.
In addition, among the present invention, medium substrate can be processed by ceramic material, macromolecular material, ferroelectric material, ferrite material or ferromagnetic material.Preferably, being processed by macromolecular material, can be macromolecular materials such as FR-4, F4B particularly.
Among the present invention, first sheet metal and second sheet metal are copper sheet or silver strip.Be preferably copper sheet, cheap, conduct electricity very well.
Among the present invention, first feeder line, second feeder line, the 3rd feeder line and the 4th feeder line are selected for use with first sheet metal and the same material of second sheet metal and are processed.Be preferably copper.
Said among the present invention " asymmetrical first micro groove structure 41 and second micro groove structure 42 " is meant, both do not constitute axially symmetric structure first micro groove structure 41 and second micro groove structure 42.In other words, promptly can not find a symmetry axis, win micro groove structure 41 and second micro groove structure, 42 relative these symmetry axis are symmetrical set on a surface.
In like manner, said among the present invention " asymmetrical the 3rd micro groove structure 41 and the 4th micro groove structure 42 " is meant, both do not constitute axially symmetric structure the 3rd micro groove structure 71 and the 4th micro groove structure 72.In other words, promptly can not find a symmetry axis, make the 3rd micro groove structure 71 and the 4th micro groove structure 72 relative these symmetry axis be symmetrical set on the b surface.
Among the present invention; First micro groove structure 41 and second micro groove structure, 42 structures are asymmetric; Therefore the 3rd micro groove structure 71 and the 4th micro groove structure 72 structures are asymmetric, and two locational electric capacity can be different with inductance, thus at least two different resonance points of generation; And the difficult counteracting of resonance point, help the multimodeization that realizes that antenna is abundant.
The version of first micro groove structure 41 of the present invention and second micro groove structure 42 can be the same, also can be different.And the degree of asymmetry of first micro groove structure 41 and second micro groove structure 42 can be regulated as required.In like manner, the version of the 3rd micro groove structure 71 of the present invention and the 4th micro groove structure 72 can be the same, also can be different.And the degree of asymmetry of the 3rd micro groove structure 71 and the 4th micro groove structure 72 can be regulated as required.Thereby realize abundant adjustable multimode resonance.
And the present invention as required, on a slice sheet metal, more micro groove structure can also be set, so that described antenna has the different resonant more than three.
Concrete, the asymmetric situation among the present invention can have following embodiment.
Shown in Figure 1 is the structural representation of said antenna first embodiment.Fig. 2 is its another visual angle figure.In the present embodiment; As shown in Figure 1; Be in medium substrate a surface first micro groove structure 41 and second micro groove structure 42 its be opening helical ring structure, first micro groove structure 41 and second micro groove structure 42 do not communicate, but the difference of its size causes the asymmetric of the two structure; Equally, as shown in Figure 2, be in medium substrate b surface the 3rd micro groove structure 71 and the 4th micro groove structure 72 its be opening helical ring structure, but the difference of its size causes the asymmetric of the two structure; Make antenna have plural at least resonance frequency.In addition; In the present embodiment; Lip-deep first sheet metal 4 of medium substrate a, first feeder line 2, second feeder line 3, first micro groove structure 41 and second micro groove structure 42 overlap with second sheet metal 7, the 3rd feeder line 8, the 4th feeder line 9, the 3rd micro groove structure 71 and the 4th micro groove structure 72 respectively in the projection on b surface, and the benefit of doing like this is a simplification technology.
Shown in Figure 3 is the structural representation of said antenna second embodiment.Because the structure on medium substrate b surface is identical with the structure on a surface, so figure has only represented the structure of a face.In the present embodiment; Be in medium substrate a surface first micro groove structure 41 and second micro groove structure 42 its be opening helical ring structure; And has identical size; First micro groove structure 41 and second micro groove structure 42 do not communicate, but because first micro groove structure 41 and 42 the two the locational setting of second micro groove structure cause the asymmetric of the two structure.
