The1st contact 5 is configured in and is arranged on thecontact 13 corresponding positions of housing one side of circular arc ofhousing 11, whenantenna 10 rotary verticallies immediately, thecontact 5 of the1st antenna element 1 contacts with thecontact 13 of housing one side, and the2nd contact 6 is to be configured in and to be arranged on the contact 13 ' corresponding position of housing one side of circular shape ofhousing 11, whenantenna 10 rotary verticallies immediately, thecontact 13 of thecontact 6 of the2nd antenna element 2 and housing one side ' contact.
In addition, thecontact spring 15,15 ' the elongation effect and hold potential energy arranged, thereby make thecontact antenna box contact
Because thisantenna 10 has above-described structure, so show overhanging setting when the1st antenna element 1 fromhousing 11, then the1st contact 5 contacts with thecontact 13 of housing one side, and the1st antenna element 1 is connected withcircuit 14 in the housing by match circuit 8.
In addition, if withantenna 10 Rotate 180s °, 2 of the 2nd antenna elements are shown overhanging setting fromhousing 11, thecontact 13 of the2nd contact 6 and housing one side ' contact, and the2nd antenna element 2 is connected withcircuit 14 in the housing by match circuit 8.At this moment, the1st antenna element 1 is rotation simultaneously also, and when therefore contacting in thecontact 13 of the1st contact 5 and housing one side was disconnected, the1st antenna element 1 just was incorporated in the recess.
In addition, though be the explanation that to be example carry out theantenna 10 of this variation of variation with the 5th example, but this fact of two sides that each antenna element is configured inhousing 11 respectively is not limited to the antenna of the 5th embodiment, also can be suitable for for the 1st～the 4th antenna.
Though more than theantenna 10 of Shuo Ming the 1st embodiment to the 5 embodiment of the present invention is to have the1st antenna element 1 and the2nd antenna element 2, but electrical length according to each antenna element, will be with independent, or shared match circuit equipment is inantenna 10 or in thehousing 11, thereby can adjust the impedance of circuit in each antenna element and the housing, make it coupling.
The impedance operator of each antenna element of antenna of thepresent invention 10 shown in Figure 11 is to use with indication part that the SWR of each antenna element is roughly 1 in the frequency, is good antenna performance.Yet, in existing antenna, owing to can not adjust, as shown in Figure 10, be that the SWR of each antenna element under the condition of frequency of utilization is in an aggravated form with indication part to the impedance of each antenna element.
As the above explanation of doing, antenna of the present invention is not only just made the form that can rotate and can take in, but also is must want in running order as prerequisite with in 2 antenna elements either party.
In addition, the structure that is used for the feeder equipment of connection layout 5 (Fig. 7) andantenna 10 shown in Figure 6 andhousing 11 1 sides is not limited to the embodiment shown in each figure at its place, also is applicable to other embodiment certainly.
In addition, each antenna element should be able to use the antenna element of different shape in each embodiment.
The present invention's picture as previously discussed, feeder equipment is to be connected to the antenna that has 2 antenna elements is made and can be rotated, and on the antenna element of erectting on the assigned position, therefore, there is no need in antenna, to be provided with insulated part, so the main frame that has this antenna can be carried out miniaturization.Therefore, be applicable to the machine of portable usefulness, especially be suitable for most in portable wireless telephone, using.
In addition, also can therefore not only each each antenna element can be on insulator, formed, the characteristic of each antenna element good characteristic can also be made among the plant antenna in the match circuit.
In addition, antenna can be taken in by rotation, by form antenna element on insulator, just can make tabular flexible antenna.Meanwhile, can also make its miniaturization.In addition, carry out operations such as fine finishining and winding around, thereby can be convenient to make owing to unnecessary.
