To being abreast arranged.
Due to there is the configuration of insulation board 130 Yu metal wire 135 between radiator 110 and circuit board 150, radiator 110 with
Metal wire 135 will not be directly electrically connected.Since radiator 110 and metal wire 135 will not be directly electrically connected, radiator 110
It will not be interfered with each other between metal wire 135, preferable signal can be obtained.
Please refer to Fig. 4.Fig. 4 is to be illustrated according to a kind of the three-dimensional of antenna assembly 100 of some embodiments of the content of present invention
Figure.In some embodiments, slot 115 is L-type, and metal wire 135 is F type.Metal wire 135 includes input terminal 135B, to
Receive signal.
As shown in figure 4, slot 115 includes long side 115A and short side 115B.Long side 115A is parallel to X-direction, short side
115B is parallel to Y-direction.X-direction is orthogonal with Y-direction.Metal wire 135 includes long side 135A.The long side of metal wire 135
The short side 115B of 135A and slot 115 has distance D1 in the X direction.In addition, slot 115 and metal wire 135 top in the Y direction
Divide overlapping.
Under double frequency mode, antenna assembly 100 includes fundamental frequency mode and frequency multiplication mode.For example, fundamental frequency mode with
The combination of frequency multiplication mode can be the global positioning system (GPS) of frequency about 1.5GHz and the bluetooth of frequency about 2.4GHz.
Since fundamental frequency mode changes depending mainly on the length of the long side 115A of slot 115, and frequency multiplication mode is depending mainly on metal
Line 135 changes relative to the position of the short side 115B of slot 115 in the X direction.It in the present invention, can be by adjusting F type gold
The relative distance D1 of the short side 115B of the long side 135A and slot 115 that belong to line 135 in the X direction, is not influencing fundamental frequency mode
The frequency of frequency multiplication mode is only adjusted in the case where frequency.In some embodiments, distance D1 can be 3 millimeters, 5 millimeters or 7 millimeters.
Distance D1 is bigger, and the frequency of frequency multiplication mode is higher.For example, the frequency of frequency multiplication mode when distance D1 is 7 millimeters is higher than distance D1
The frequency of frequency multiplication mode when being 5 millimeters.Regardless of distance D1 is 7 millimeters or 5 millimeters, the frequency of fundamental frequency mode does not change.
Conversely, can also be by adjusting the length of the long side 115A of slot 115, the case where not influencing the frequency of frequency multiplication mode
Under only adjust the frequency of fundamental frequency mode.For example, by metal wire 135 in the X direction relative to the short side 115B's of slot 115
Position is fixed, only changes the length of the long side 115A of slot 115, and the frequency of fundamental frequency mode can be changed.
That is, in the present invention, frequency multiplication mode can be only adjusted in the case where not influencing the frequency of fundamental frequency mode
Frequency, or only adjust in the case where not influencing the frequency of frequency multiplication mode the frequency of fundamental frequency mode.
In some embodiments, as shown in figure 4, slot 115 includes open end 115C and closed circuit end 115D.In some realities
It applies in example, the length of the long side 115A of slot 115 is a quarter times of the wireless signal wavelength of antenna assembly 100.Some
In embodiment, radiator 110 includes metal fuselage.For example, can using the metal fuselage of hand-held device (such as mobile phone) as
The radiator 110 of antenna assembly 100.In some embodiments, insulation board 130 is plastic plate.In some embodiments, insulation board
130 material is glass mat FR4.
In some embodiments, circuit board 150 is printed circuit board (PCB).In some embodiments, signal input module
140 be elastic slice, to make metal wire 135 mutually be conducted with circuit board 150.

The metric data of antenna, curve 530 are the metric data of antenna assembly 100 of the invention.By experimental data figure 500 it can be seen that,
The Frequency point of traditional slot type antenna is higher than the Frequency point of antenna assembly 100 of the invention.For example, as shown in figure 5, passing
The Frequency point of the fundamental frequency mode of system open circuit slot antenna is about 1.73GHz, and the fundamental frequency mode of antenna assembly 100 of the invention
Frequency point is about 1.55GHz, lower than the Frequency point of the fundamental frequency mode of tradition open circuit slot antenna.
Since antenna size and frequency are inversely proportional, if it is desired to so that tradition open circuit slot antenna is reached day of the invention traditional thread binding
100 Frequency point is set, the antenna length of tradition open circuit slot antenna need to be increased.That is, relative to tradition open circuit slot
Antenna, antenna assembly 100 of the invention can be used shorter antenna length and reach identical Frequency point.
For example, in some embodiments, if with traditional open circuit slot antenna, slot length need to be 47 millimeters of
Required frequency can be reached, and in antenna assembly 100 of the invention, slot length only needs effectively reach contracting for 31 millimeters
The effect of smallization product length, on production advantageously.
