The reserved location in space is not limited to above-mentioned several form on the dual polarized antenna 100 of the present invention, as long as the space is arranged on the dual polarized antenna.For example, the space can also be arranged on the medium substrate.
Described 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 by adding the electronic component of different parameters, can realize the adjustable of antenna performance parameters.Adding electronic component in the space can have following several situation because the b face of medium substrate is identical with a face, so following explain with a face:
(1) in the space of the first feeder line, the second 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 during for 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, if thereby the too large alternating signal of inductance value will be had influence on by perceptual electronic component consumption the radiation efficiency of antenna.Certainly also may add resistance to improve the radiation resistance of antenna in the space on the first feeder line, the second feeder line.Certainly, also a plurality of spaces can be set on the first feeder line and the second feeder line, segment space embedded resistor wherein, segment space embeds perceptual electronic component, has both realized the adjusting of operating frequency, can improve again the radiation resistance of antenna.Certainly according to other needs, also can only in segment space, add electronic component, other space wire short circuit.
(2) embed the capacitive electronic component in the space between the first feeder line 2 and the first sheet metal 4, between the second feeder line 3 and the first sheet metal 4.Here regulate signal coupling between the first feeder line 2, the second feeder line 3 and the first sheet metal 4, using formula by embedding the capacitive electronic component:
Square being inversely proportional to of the size of capacitance and operating frequency as can be known, so when the operating frequency that needs during for 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 the first feeder line 2, the second feeder line 3 and the first sheet metal 4, preset a plurality of spaces, in not being connected with the space of electronic component, adopt the wire short circuit.
(3) the perceptual electronic component of embedding and/or resistance are arranged in the space 6 on the first metal routing 43 of the 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 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 to embedding perceptual electronic component or resistance, then decide as required.In not embedding the space of electronic component, adopt the wire short circuit in addition.
(4) in the space 6 of the first micro groove structure 41 and 42 reservations of the second micro groove structure, embed the capacitive electronic component.Embed the resonance performance that the capacitive electronic component can change the first sheet metal, 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 larger, and then passband is narrower, the less then passband of Q is wider.Other has: Q=wL/R=1/wRC, and wherein, Q is quality factor; Supply frequency when w is circuit resonance; L is inductance; R is the resistance of string; C is 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.
Dual polarized antenna of the present invention 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, namely realized versatility, therefore can significantly reduce production costs.
Described space of the present invention can be pad, also can be a vacancy.The structure of pad 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.
