The said electronic component of the 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 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, 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 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 according to other needs, also can only in segment space, add electronic component, the lead short circuit is used in other space.

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 between first feeder line 2 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) embed perceptual electronic component and/or resistance 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 w0 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.
The antenna of the utility model 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.
The said space of the 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.
In addition, in the utility model, 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.
In the utility model, first sheet metal and second sheet metal are copper sheet or silver strip.Be preferably copper sheet, cheap, conduct electricity very well.
In the utility model, first feeder line, second feeder line are selected for use with first sheet metal and the same material of second sheet metal and are processed.Be preferably copper.
