Description
Technical field
The present invention relates to RF unit and portable communication device, make and in multi-part formula portable communication device, to use the rigidity coaxial conductor.
Background technology
A trend in the design of the portable communication device such such as mobile phone is so-called clam-shell type of phone.The phone of another kind of type is a jack-knife type of phone, and the third is a flip-type of phone.The phone of these types all is non-bar type, is made up of two major parts, normally a upper part and a lower part.
Clam-shell type of phone has the feasible advantage that sizable keyboard and big display are mated.
Because the characteristic of design and for the needs of the hope of optimum performance, common practice is that electronic installation is placed on the lower part of phone and antenna is placed on upper part.For this reason, radio frequency (RF) signal demand transmits between two parts.
The RF signal transmits between two parts by signal guidance being crossed the compliant conductive coaxial cable that is placed the hinge area that connects lower part and upper part usually.
In U.S. patent documents US 5,561,437, a kind of two position folded doublets are disclosed, therefore it be used in two component type mobile phones.This antenna has in the first of the flip potion of mobile phone with at the second portion of the major part of mobile phone.These parts are connected to each other by the flexible tape conductor that is placed in the hinge area between first and second parts.
Therefore aforesaid technology uses flexible tape conductor.
In another kind of prior art mobile phone, coaxial cable is used to allow the RF signal to be sent to another part of phone from a part of two component type mobile phones.Like this have two parts that can relative motion and the coaxial cable of phone in hinge area that this two parts can be rotated relative to each other is debatable.
In order to allow to open and close two component type phones, coaxial cable must allow crooked and or twist motion.So these cables are flexible, so that allow such motion.
Yet use flexible coaxial cable that such problem is arranged: open and close the external force that motion need be high in order not cause to overcome when the user operates mobile phone, the external diameter that requires such cable is little.But the diameter that coaxial cable is enough little has increased the loss of radiofrequency signal in cable.
Use another shortcoming of flexible coaxial cable to be, be difficult to by rights the screen of cable to be connected to circuit and connect the position.If very poor ground connection, then the RF signal can generate in the zone of other sensitivity of phone and disturb.And when very poor ground of coaxial cable ground connection, antenna radiation performance also is difficult to optimization.
The shortcoming of current technology is the difficulty of fixing flexible cable in hinge area.Cable is easy to be extruded between machine components, and this applies the aforesaid power of overcoming and this also may be reduced in the conveying function of the RF signal of hinge area inner cable.
So, wish to overcome the above-mentioned flexible conductor of in two component type mobile phones, using and transmit the shortcoming of RF signal.
