Simultaneously, for the electromagnetic parameter of adjusting the utility model antenna of aspect more, it is wider to make it applicable surface, also is preset with the space 6 that embeds for all kinds of electronic components in the utility model antenna.
In the utility model, described space 6 is arranged between first feeder line 11, first feeder line 11 and first sheet metal 10, reaches at least one of first sheet metal, 10 these three positions.Described space also is arranged between second feeder line 21, second feeder line 21 and second sheet metal 20 and reaches at least one of second sheet metal, 20 these three positions.Preferably, the setting of a plurality of spaces 6 on antenna as shown in Figures 1 and 2, that is, on the A of medium substrate face, between first feeder line 11, first feeder line 11 and first sheet metal 10, and first sheet metal, 10 these three positions on the space that electronic component embeds all is set.Wherein, space on first sheet metal 10 comprises and is arranged on the space on first metal routing 14 and is arranged on space on first micro groove structure 12 and second micro groove structure, and is arranged on first metal routing, 14 edges that space 6 on first micro groove structure 12 and second micro groove structure 13 connects both sides respectively.Equally, on the B of medium substrate face, the space that electronic component embeds is set all between second feeder line 21, second feeder line 21 and second sheet metal 20 and second sheet metal, 20 these three positions.Wherein, space on second sheet metal 20 comprises the space that is arranged on second metal routing 24, and be arranged on space on the 3rd micro groove structure 22 and the 4th micro groove structure 23, and be arranged on second metal routing, 24 edges that space 6 on the 3rd micro groove structure 23 and the 4th micro groove structure 23 connects both sides respectively.
The reserved location in space is not limited to above-mentioned several form on the antenna of the present utility model, as long as the space is arranged on the antenna.For example, the space can also be arranged on the medium substrate.
Described electronic component of the present utility model 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 by adding the electronic component of different parameters.Adding electronic component in the space can have following several situation because the B face of medium substrate is identical with the A face, so below do explanation with the A face:
(1) in the space of first feeder line, add perceptual electronic component, using formula:
Square being inversely proportional to of the size of inductance value and operating frequency as can be known, so when the operating frequency that needs be low operating frequency, can be by suitable embedding inductance or the realization of perceptual electronic component.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 may in the space of first feeder line, add resistance to improve the radiation resistance of antenna.Certainly, have also on first feeder line a plurality of spaces can be set, segment space embedded resistor, segment space embed perceptual electronic component, have both realized the adjusting of operating frequency, can improve the radiation resistance of antenna again.Certainly, also can only in segment space, add electronic component, other space lead short circuit according to other needs.
(2) embed the capacitive electronic component in the space between first feeder line 11 and first sheet metal 10.Here the signal of regulating between first feeder line 11 and first sheet metal 10 by embedding capacitive electronic component is coupled using formula:
Square being inversely proportional to of the size of capacitance and operating frequency as can be known, so when the operating frequency that needs be low operating frequency, can be by suitable embedding capacitive electronic component realization.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 may exceed the scope of 0-2pF.Certainly, also can between first feeder line 11 and first sheet metal 10, preset a plurality of spaces, in not being connected with the space of electronic component, adopt the lead short circuit.
(3) embed perceptual electronic component and/or resistance in the space 6 on first metal routing 14 of first sheet metal.The purpose that embeds perceptual electronic component herein 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 herein.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 12 and second micro groove structure 13, 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 pass of passband BW and resonance frequency w0 and quality factor q is: BW=wo/Q, and this formula shows that Q is big more, and 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, and by the Q=wL/R=1/wRC formula as can be known, Q and C are inverse ratio, therefore, can reduce the Q value by adding the capacitive electronic component, and passband is broadened.
Antenna of the present utility model can be the same structure before not adding any element, just by 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.
Described space of the present utility model 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.
