The radiant body 32 of interval setting one first and one the on one surface of the relative first circuit board 10 of the second circuit board 30
Two radiant bodies 34.In the present embodiment, first radiant body 32 is smaller in size than the second radiant body 34.Specifically, channel radio is worked as
When the lid opposing body of T unit 200 closes, first radiant body 32 is same with 2 first shell fragments 124 of first antenna unit 12
When contact, so first main radiator 122 is electrically connected with the first radiant body 32 by 2 first shell fragments 124, and constitutes one
Annular（LOOP）Antenna.The current path of the loop aerial and the wavelength of WIFI signal into special ratios so that first antenna list
The radiant body 32 of unit 12 and first is provided commonly for receiving and dispatching WIFI signal.Meanwhile, the antenna element 14 of the second radiant body 34 and second
Second shell fragment 144 is contacted, and so second main radiator 142 is electrically connected with the second radiant body 34 by the second shell fragment 144, with
Increase current path.Current path and the wavelength Cheng Te of gps signal that second antenna element, 14 and second radiant body 34 is formed
Certainty ratio, for use in transmitting-receiving gps signal.
The slide mechanism 50 includes slide block 52 and slide rail 54, and in the present embodiment, the slide rail 54 is located at first circuit board 10
On, the slide block 52 can slide on second circuit board 30 with respect to slide rail 54.It is appreciated that the slide block 52 may also set up with
On the lid 230 of radio communication device 200, the slide rail 54 may also set up on body 210, with by driving lid 230 relative
Body 210 slides, and then makes the relative first circuit board 10 of second circuit board 30 slide.
The operation principle of the antenna structure 100 is further illustrated below：
Fig. 4 is referred to, when radio communication device 200 is in closure state, second circuit board 30 is located at first circuit board
10 tops.Now, the common transmitting-receiving WIFI signal of 12 and first radiant body of first antenna unit 32, the second antenna element 14 and second
Radiant body 34 receives and dispatches gps signal jointly.During the radio communication device 200 hand-held due to user, handss easily cover this first day
The radiant body 32 of line unit 12 and first, and cause the transmitting-receiving of WIFI signal to be affected.Therefore, when the normal transmitting-receiving WIFI signal of needs
When, lid 230 can be promoted, make the relative first circuit board 10 in the presence of slide mechanism 50 of second circuit board 30 slide.Now,
2 first shell fragments 124 are separated with the first radiant body 32, and the second shell fragment 144 is separated with the second radiant body 34 so that first antenna list
Gps signal, the transmitting-receiving WIFI signal of the second antenna element 14 are received and dispatched by unit 12.Unlapped second antenna element 14 of handss can so be passed through
Normal transmitting-receiving WIFI signal.
Fig. 5 is referred to, in the same manner, when radio communication device 200 is in open mode, because handss easily cover this first day
Line unit 12, and cause the transmitting-receiving of gps signal to be affected.Therefore, when normal transmitting-receiving gps signal is needed, can reversely promote lid
Body 230, makes the relative first circuit board 10 of second circuit board 30 slide until the first radiant body 32 with 2 first shell fragments 124 while connect
Touch, the second radiant body 34 is contacted with the second shell fragment 144.Now, can be common with the second radiant body 34 by the second antenna element 14
Normal transmitting-receiving gps signal.
It is appreciated that the antenna structure 100 of this case is not limited to switch WIFI signal and gps signal, it can also be used to switch
Other wireless signals, such as bluetooth（Bluetooth, BT）The transmitting-receiving of signal, now need to only adjust the shape of corresponding radiant body
And size.
It is appreciated that the antenna structure 100 of this case is not limited to the switching between two kinds of wireless signals, it can also be used to switch
Three kinds and more than three kinds of signal, now only need to it is corresponding increase main radiator and shell fragment on first circuit board 10, the
Increase radiant body on two circuit boards 20.
The antenna structure 100 of the present invention on first circuit board 10 by arranging first antenna unit 12 and the second antenna list
Unit 14, and the first radiant body 32 and the second radiant body 34 are set on second circuit board 30, to be made respectively by slide mechanism 50
First antenna unit 12 is contacted or separated with the first radiant body 32, and the second antenna element 14 is contacted with the second radiant body 34 or divided
From, and then when radio communication device 200 is opened or closed, realize the switching between signal.When user hand-held wireless communication
Device 200 and when affecting a certain signal transmitting and receiving efficiency, radiant body electrical length can be adjusted and adjusted by the antenna structure 100
The frequency of its receiving and transmitting signal, the signal for making the transmitting-receiving of antenna structure 100 meets transmitting-receiving duty requirements, is easy to radio communication device
200 stably communicate.
