When, can also reduce static discharge (Electrostatic Discharge, the ESD) effect of electronic installation 10.
Fig. 3 show the structural representation according to antenna structure in electronic installation in one embodiment of the invention.
Wherein, the antenna structure 100 shown in Fig. 3 is shown in Fig. 2, using casing BC in side S1
The antenna structure 100 of setting.Refer to Fig. 3, antenna structure 100 be arranged at the side with casing it
On one (such as shown in Figure 2 side S1), including major trough hole 110, pilot trench hole 131～134 and
Feeding portion 120.Side S1 of the major trough hole through the casing BC of metal material, wherein major trough hole 110 is
Grooved bore, with openend OE and closed end CE.Similar in appearance to major trough hole 110, pilot trench hole 131～
134 through casing BC side S1 and be adjacent to major trough hole 110.But different from major trough hole 110
It is that pilot trench hole 131～134 is locked groove hole.The bearing of trend in pilot trench hole 131～134 is parallel to major trough hole 110
Part.Specifically, as shown in figure 3, major trough hole 110 is bent with two, referred to herein as first
The bending B2 of bending B1 and second.And major trough hole 110 in first bending B1 and second bending B2 it
Between part bearing of trend it is then parallel with the bearing of trend in pilot trench hole 131～134.That is,
In the present embodiment, major trough hole 110 and pilot trench hole 131～134 can be considered in principle and set side by side mutually
Put.
Feeding portion 120 has load point FP, wherein side S1 of the feeding portion 120 parallel to casing BC
And it is not connected with the side S1 of casing BC, wherein feeding portion 120 is in the side S1 of casing BC
Orthographic projection and the part in major trough hole 110 and partly overlapping for pilot trench hole 131～134.From the figure 3, it may be seen that
The orthographic projection of feeding portion 120 is across on the major trough hole 110 of part.In other words, feeding portion 120
Bearing of trend is in principle with the part in the bearing of trend in pilot trench hole 131～134 and major trough hole 110 (i.e.,
The part of two of major trough hole 110 bendings between B1, B2) bearing of trend it is vertical.
As the narration of Fig. 2 understands that casing BC can be considered system ground, and the side of casing BC
Side S1 is connected with system ground.Under such setting, antenna structure 100 is i.e. using major trough
The radiofrequency signal of correspondence frequency band is received and dispatched as slot antenna in hole 110.Specifically, electronic installation 10 (connects
Radio frequency signal transceiving module in the electronic installation of the load point FP for being connected to feeding portion 120) by feed-in
Portion 120 couples major trough hole 110 and produces first that first mode is located at first band with headend frequency
Radiofrequency signal.Wherein, slotted eye length L2 (or overall length L1 of antenna structure) in major trough hole can be set
It is set to the quarter-wave for being similar to the first radiofrequency signal.
In the present embodiment, antenna structure 100 further comprises switch SW, as illustrated in fig. 3, bridging
In the both sides in major trough hole 110.When switching SW and closing and turn on the both sides in major trough hole 110, electronics dress
Put 10 (such as the radio frequency signal transceiving modules in electronic installation) and major trough hole is coupled by feeding portion 120
110 and produce second mode with headend frequency be located at second band the second radiofrequency signal.It is such
Setting is so that the major trough hole 110 as antenna, and slotted eye length that can be directly shorter produces mode, with
The radiofrequency signal of transmitting-receiving relative high frequency.Wherein major trough hole is similar to from the slotted eye length of switch to the openend
The quarter-wave of the second radiofrequency signal.In the present embodiment, the first mould produced by major trough hole 110
First band corresponding to state is 800MHz to 900MHz.Major trough hole 110 is subject to switch SW short-circuit
