The reserved location in space is not limited to above-mentioned several kinds of forms 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.
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 frequency of operation of inductance value; So, can realize through suitable embedding inductance or perceptual electronic component when the frequency of operation that needs is when hanging down frequency of operation.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 frequency of operation, 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 frequency of operation of capacitance; So when the frequency of operation that needs is when hanging down frequency of operation, 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 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.
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.
