    摘要: A high frequency switch used for a mobile communication apparatus, such as, a portable telephone or the like is provided. The dual band switch may be in an ON or an OFF state in two bands. The dual band switch may comprise a series circuit including a PIN diode and a compensation circuit. The compensation circuit may be formed having at least two series resonance points and one parallel resonance point. The circuit arrangement allows the impedance of the compensation circuit, which is capacitive at low frequency close to a direct current, to become inductive after a first series resonance point, so that a parasitic capacitance of the diode may be canceled in a first band. The impedance of the compensation circuit may also become inductive after a parallel resonance point and the following series resonance point, so that a parasitic capacity of the PIN diode may be canceled in a second band.

    摘要: A small antenna device having a wide frequency band suitable for being built in mobile communications apparatuses. This antenna device includes a planar radiating element (radiating plate) and a grounding plate provided in parallel to and facing the radiating plate. A feeding line is disposed at approximately the end center of the radiating plate, and supplies high-frequency signals. A shorting portion shorts the radiating plate and grounding plate at near the feeding line. A slit is provided at an end face of the radiating plate approximately opposing the feeding line to form two resonators. A coupling level between two resonators is optimized by adjusting the shape or dimensions of this slit, or loading a reactance element or conductive plate on this slit. Accordingly, a small and short antenna with a preferred characteristic is achieved.

    摘要: The present invention relates to an antenna device used in mobile communication apparatus such as cellular phones, and which achieves good transmission and reception of information in more than one frequency band. The present invention aims at providing antenna devices and mobile communication apparatus using the devices, which allow an easy and wide ranging adjustment of the impedance properties of the antenna as well as their productive mass production. To satisfy the foregoing purpose, the antenna device of the present invention includes a) a spiral-shaped first antenna element (1) of which one end is open and the other end is electrically connected to a high frequency circuit inside a communication terminal; and b) a second antenna element (2) having both ends being open, and which is insulated from and disposed on either outer or inner surface of the first antenna element (1). The impedance properties of an antenna can be adjusted by changing the disposing position of the second antenna element (2).
