It is not to be provided only with earth point and distributing point on the circuit board in the present embodiment, be additionally provided with electric capacity.Those skilled in the art should
When knowing, electric capacity is it can be appreciated that capacitor, and it is electric capacity that generally referred to as it, which accommodates the ability of electric charge, and its English name is
Capacitor is represented with letter C.Capacitor, it is the container of dress electricity as its name suggests, is a kind of device for accommodating electric charge.
Antenna in the present embodiment includes antenna body, and the grounding pin and feed that are connected respectively with antenna body draw
Pin.In the present embodiment, antenna body is process by a sheet metal.Grounding pin and feed pin difference on antenna body
For contacting and being electrically connected with the earth point on circuit board and distributing point.
Specifically, grounding pin is located at one end of antenna body.Feed pin is located at the interlude of antenna body, makes day
Line body is divided into first paragraph portion and second segment portion on the basis of feed pin.The integrated knot in first paragraph portion and second segment portion
Structure, and in level.In the present embodiment, grounding pin and feed pin are parallel to each other.More specifically, grounding pin and first
Section portion is mutually perpendicular to, and feed pin is also mutually perpendicular to first paragraph portion, and it is in F shapes to make antenna.
The one end in first paragraph portion is connected with grounding pin, and the other end in first paragraph portion connects with feed pin, second segment portion
One end connected with feed pin, grounding pin is connected with electric capacity.
Wherein, feed pin, first paragraph portion, grounding pin and electric capacity form the first signal resonant branch, feed pin and
Second segment portion forms secondary signal resonant branch, wherein, the first signal resonant branch and secondary signal resonant branch are used to receive
Different signal, for example, the first signal can be gps signal, and secondary signal can be WI-FI signals.
Therefore, if using the first signal as gps signal, secondary signal is the antenna of the present embodiment offer exemplified by WI-FI signals
In attachment structure, there is the first signal resonant branch formed by feed pin, first paragraph portion, grounding pin and electric capacity, and
The secondary signal resonant branch formed by feed pin and second segment portion.Feed pin is located at antenna body stage casing position to the right
Put, grounding pin is located at the high order end of antenna body, and grounding pin connect an electric capacity to.Because the logical low frequency of electric capacity hinders
High-frequency effects, from feed point direction toward the place of left direction, the loop of one similar cycle form of formation, it is allowed to the electricity of rather low-frequency
Stream passes through, and by the distance between Reasonable adjustment feed point and place, and selects the capacitance of suitable size, will produce one
GPS resonance, and the branch on the right side of feed point then produces the Wi-Fi resonance of high frequency.Or fixed in distributing point and earth point position
In the case of, the size for the capacitance contacted by adjusting place can also adjust GPS resonance frequency deviation.This kind of antenna connection knot
Structure compared with prior art, can be by adjusting position or the capacitance Regulate signal resonance of earth point, rather than prior art
The mode Regulate signal resonance of middle adjustment antenna body length, so as to reduce requirement of the antenna to space.
In the present invention, unless otherwise clearly defined and limited, fisrt feature can be with "above" or "below" second feature
It is that fisrt feature and second feature directly contact, or fisrt feature and second feature pass through intermediary mediate contact.
Moreover, fisrt feature second feature " on ", " top " and " above " can be fisrt feature in second feature
Surface or oblique upper, or be merely representative of fisrt feature level height and be higher than second feature.Fisrt feature is in second feature " it
Under ", " lower section " and " following " can be fisrt feature immediately below second feature or obliquely downward, or be merely representative of fisrt feature water
Flat height is less than second feature.
