Description

^60253 IX. Description of the invention: [Technical field to which the invention pertains] (The present invention relates to an RF unit and a portable communication device for utilizing a rigidity in a portable communication device of a plurality of parts Coaxial conductors. [Prior Art] There is a tendency to design a device for private use, such as a mobile phone, which is a so-called shell phone. Another type of phone is a sapphire phone, and the third is a folding machine. Telephones. These types of telephones are non-stick type and consist of two main parts 'usually a high part and a lower part. The shell type has the advantage of being able to accommodate a large The display fits into a tiny external dimension with a fairly large keyboard. a Due to the nature of the design and the desire for optimal performance, the usual way is to place the electronics in the lower part of the phone.

ίHigh part. For this reason, it is necessary to transmit a radio frequency between the two (U connects the lower part and the high part of the conductor in the two parts, usually through the guiding signal through the hinge elastic range of the hinge part that is placed through the part) The RF signal is transmitted between the cables. The entangled bipolar patent document No. 5,561, 437 discloses a dual position: a polar antenna, which can be used in a two-part type of mobile phone. - Partially, the second part of the main part (4) of the mobile phone is covered by the mobile phone. These stations = the first and the second H chain _" with conductors and 99673.doc 1360253 are interconnected. Thus, the technique disclosed above utilizes an elastic strip conductor. In another advanced technology, a mobile phone coaxial cable is used to transmit RF signals from a part of a two-part mobile phone to the telephone. Another. A wound that has two parts that can move relative to the other, and wherein each of the parts can be rotated in relation to the other, the coaxial cable in the range of the hinge will Problem β

In order to open and close a pair of telephones, the coaxial cable must be capable of being tested and/or twisted. These cables are therefore resilient to provide these movements. However, there is a problem with the use of flexible coaxial cables, that is, the outer diameter of the cables needs to be extremely small' so as not to provide a strong counteraction to the opening or closing movement exerted by the user when operating the mobile phone. However, a sufficiently small diameter of the 'coaxial cable' will increase RF leakage in the cable.

Another disadvantage of using an elastic coaxial cable is that it is difficult to connect the screen shield of the cable to the electronic ground in a suitable manner. If poor grounding occurs, the RF signal will cause interference in other sensitive areas within the phone. In addition, when the coaxial cable is poorly grounded, the antenna radiation performance may not be optimized. A disadvantage of the prior art is that it is not easy to secure the elastic gauge line at the hinge position. The cable is easily squeezed between the various mechanical details, which exerts a reaction force as described above, and which also reduces the RF signal transmission efficiency of the cable over the hinge range. Therefore, it would be desirable to overcome the above drawbacks of utilizing a resilient 99673.doc 1^00253 conductor for RF signal transmission in a dual-port mobile phone.
