摘要： A device and method for receiving signals in the radio frequency range by a mobile phone. The device comprises a radiator part having a ¼ wave electric length (or an odd integral multiple thereof) for receiving the signals, wherein the feed of the radiator part is tapped for impedance matching. In order to reduce to the size of the device so that it can be implemented in a mobile phone or a communicator, the radiator part is placed at the proximity of a frame having a medium relative permittivity for dielectric loading. The relative permittivity of the frame ranges from 2 to 50 in the radio frequency range. Preferably, one or more devices are placed at one of the corners of the mobile phone body so that one device will be selected to receive the signals based on the interaction between the radiation modes of the device and the radiation field of the mobile phone body in order to achieve a right-handed, circular or elliptical polarization.

摘要： An RF antenna having a non-planar resonating region for radiating or receiving electromagnetic waves in order to convey communication signals between two electronic devices via a radio link. The resonating region is folded into at least two sections so that the radiating surface of one section is located on a different plane from the radiating surface of the other section. In order to optimize the input impedance of the antenna, an impedance matching part connected to the resonating region is used to provide a short circuit to the resonating region. A signal conduit part is used to feed signals to the resonating region in the proximity of the impedance matching part. Preferably, the antenna is integrated into a system connector of a hand-held communication device so as to allow the hand-held device to communicate with a communication network via a radio link.
