In the following, antenna element according to the ... of the embodiment of the present invention will be described with reference to figure 5 and Fig. 6.
Fig. 5 illustrates the overall schematic of antenna element according to the ... of the embodiment of the present invention.
As described above, antenna element according to the ... of the embodiment of the present invention includes feed end 140 and radiator 111.
As illustrated in fig. 5, which includes metal arm 141 and matching unit (not shown).
The metal arm 141 has orthogonal first part 1411 and second part 1412, the length of first part 1411
Degree is more than the length of second part 1412, and the first surface of first part 1411 and the outer cover unit 110 as radiator
111 is parallel and form capacitive coupling.In this way, capacitively coupled feed-in reduces influence of the human body for antenna performance.
In one example, as illustrated in fig. 5, the first part 1411 of metal arm 141 and second part 1412 can be with
Form the L-type stood upside down.In other words, which is mutually perpendicular to the second part 1412, and the second part
Either end in 1412 length directions in first part 1411.
In another example, the first part 1411 of the metal arm 141 and second part 1412 can also form T-type or close
Like T-type.In other words, which is mutually perpendicular to the second part 1412, and the second part 1412 is in the
The center (that is, T-type) of the length of a part 1411, or in the other positions other than center (that is, approximate
T-type).
By above-mentioned configuration, the first surface 111 of the metal arm 141 and tablet computer 400 forms inductance capacitance (LC) and shakes
Swing circuit.The second part 1412 of the metal arm 141 is equivalent to the inductance element in the LC oscillating circuits, and the metal arm 141
The combination of first part 1411 and first surface 111 be equivalent to the capacity cell in the LC oscillating circuits, and they two
Capacitive coupling is formed between person.Thus, pass through such as L-type, T-type or the gold of the metal arm 141 and tablet computer 400 of approximate T-type
Belong to the electromagnetic coupling between shell, by the energy-activation of the wireless communication module 131 in circuit board unit 130 and is transported to
Metal shell, to radiate energy in the form of an electromagnetic wave in fixed working frequency points.
Furthermore, it is possible to set the metal arm 141 to be located proximate to the edge of outer cover unit 110, for example, positioned at outer
Near the first surface 111 of the metal material of shell unit 110, to ensure that antenna current is maximum in the edge of outer cover unit 110,
To reduce the loss of metal shell conductor.
In addition, a distributing point 1413 is formed on the end of the second part 1412 of metal arm 141, the distributing point 1413
The wireless communication module 131 being connected in circuit board unit 130, to receive wireless communication module 131 as signal input point
The radiofrequency signal that middle frequency conversion component is converted, or sent to the frequency conversion component from antenna element as signal output point
Radiofrequency signal.Day can be controlled by changing the distributing point 1413 and the distance between the earth point on circuit board unit 130
The wavelength for the electromagnetic wave signal that line unit is emitted, this will be described later referring to Fig. 6.

The impedance of the LC oscillating circuits is matched always in about 50 ohms.In this way, the corresponding matching electricity being made of matching device
Road forms wideband resonance characteristic with the metal arm, to broaden the bandwidth of antenna element, and improves antenna element
Working efficiency.
Fig. 6 illustrates the partial schematic diagram of antenna element according to the ... of the embodiment of the present invention.
There is the outer cover unit 110 earth point 1111, the earth point 1111 can be located at the first table of outer cover unit 110
Inside face 111.As illustrated in FIG. 6.Such as the earth point 1111 can be arranged in it is vertical with first surface 111 and to electricity
On the metal arm or wire that the direction of road plate unit 130 is extended；Those skilled in the art be readily appreciated that when, such as
When two sides of fruit outer cover unit are non-conducting material compositions, the metal arm or wire of the setting earth point can be with
It is set directly on the inner wall of the side.
Meanwhile circuit board unit 130 has ground metal layer, which can be on printed circuit board (PCB)
Cover copper, and the metal part (for example, whole of first surface 111) on outer cover unit 110 is connected by earth point 1111
It is connected to the ground metal layer of circuit board unit 130.
Preferably, have completely on the circuit board unit 130, i.e., the ground metal layer is big on printed circuit board
The copper body of area, so that it is guaranteed that the first surface 111 of metal material is filled by earth point 1111 with the ground on circuit board unit
Tap is touched, to realize metal shell with circuit board unit 130 adequately grounded.
The signal wire of distributing point 1413 on the metal arm 141 is connected to the signal wire of wireless communication module 131, and the feedback
The ground wire of electricity point 1413 is connected to regard to near-earth in the ground metal layer of circuit board unit 130.Wherein so that distributing point 1413
Wireless communication module 131 is solved as much as possible, is connected and this metal wire with reducing, to reduce signal decaying.
In addition, when designing antenna element, the working frequency range for the electromagnetic wave that antenna element can be radiated or received
It is configured.For example, controlling the electromagnetic wave signal by changing the distance between distributing point 1413 and earth point 1111
Wavelength finds appropriate matching short dot, makes entire full metal jacket resonance in working frequency range.
For example, according to the resonance characteristic of half wavelength, can by between distributing point 1413 and earth point 1111 away from
Half from the electromagnetic wave signal wavelength for being set as being radiated, to realize relatively stable transmission characteristic.It alternatively, can be with
The a quarter for the electromagnetic wave signal wavelength that the distance between distributing point 1413 and earth point 1111 are set as being radiated, to protect
Demonstrate,prove maximum intensity transmission.
It is of the invention using the distance between distributing point 1413 and earth point 1111 are generated different matching short dots
Antenna element can also realize multiband or wideband design.
Fig. 7 illustrates the bandwidth of the bandwidth and antenna element according to the ... of the embodiment of the present invention of antenna element in the prior art
Comparison schematic diagram.
In the figure 7, expression by a dotted line is bandwidth-return loss (S11) curve of antenna element in the prior art, and
By realizing that is indicated is bandwidth-return loss (S11) curve of antenna element according to the ... of the embodiment of the present invention.
As illustrated in figure 7, it in the case of identical return loss, in other words, is imitated in the identical work of antenna element
In the case of rate, use traditional linking feeding classification (for example, metal chip antenna, printed circuit board (PCB) in the prior art
Antenna or flexible printed circuit board (FPC) antenna) antenna element bandwidth f3-f2 much smaller than according to the ... of the embodiment of the present invention
The bandwidth f4-f1 of antenna element.Accordingly, it can be seen that with traditional linking feeding classification (also known as contact feeding classification) phase
Than couple feed of the invention forms capacitive coupling using the L-type electric arm of such as bending with metal-back, counteracts electric arm itself sense
Property ingredient, and with corresponding match circuit formed wideband resonance characteristic, effectively broadened the transmission bandwidth of antenna element.
In practice, in order to enable the bandwidth of antenna can reach the standard of mobile communication or wireless data communication, for
