摘要： The present invention seeks to provide a dual mode mobile satellite communication unit, which requires low communication cost and very little battery power, does not require always carrying a large unit frame and does not always provide great weight burden on the user. A terrestrial communication portable unit (B) is detachably mounted in the mobile satellite communication unit (A). The mobile satellite communication unit (A) as base unit does not include a key operating section, a display section and a speech transducer section having a microphone and a loudspeaker, and utilizes those mechanically assembled on the portable unit (B) side for keying and other operations. In an interlocked relation to the removal of the portable unit, the stand-by state of the base unit is turned off. It is thus possible to avoid wasteful battery power consumption on the base unit side.

摘要： An apparatus for providing an antenna impedance matching network (5) that does not include mechanical switch contacts is disclosed. A retractable antenna (20) includes a conductive plate (35) moveable between the extended and retracted positions of the antenna. When the conductive plate is located in the extended position an impedance matching circuit (50) responsive to the position of the conductive plate is connected between the antenna (25) and an amplifier of a radio telephone. In response to location of the conductive plate in the retracted position, the impedance matching circuit is shorted out such that the antenna is connected directly to the amplifier via a capacitive effect between the conductive plate and a conductive coil (80) of the shorted out impedance matching circuit.

摘要： In a radio apparatus having a rod-like antenna (6), a cable (12) has one end electrically and mechanically connected to the antenna and is urged by a urging arrangement (22,24) so that it is prevented from slackening. The other end of the cable is fixed to an electrical part such as a circuit board (14) contained in a casing (4) of the radio apparatus. The antenna is stored in a storage portion (8) of the casing so as to be movable in a direction parallel to an extension axis of the antenna. It is preferable that the urging arrangement is constituted by a combination of a tension pulley (22) and a spring member (24) which is interposed between the tension pulley and the casing for urging the tension pulley to make said cable have tension.

摘要： In a multi-band antenna (10) being provided with an antenna element having an LC parallel resonance circuit (3) and a first and a second radiation element (1,2) connected to opposite ends of the LC parallel resonance circuit, the LC parallel resonance circuit is constituted by self-resonance of an inductor itself. A telescopic whip antenna may be constituted by combining a small-size antenna and a whip antenna which is receivable in a radio device casing and expandable.

摘要： The present invention provides an antenna system, which is used for a mobile wireless device and can be accommodated in or withdrawn from a telephone set main unit, whereby element length is shortened and strength is increased while avoiding deterioration of characteristics when the antenna is accommodated in the telephone set main unit. The antenna (40) comprises a helical antenna (41) having a feeding unit (42) and a whip antenna (43) having a feeding unit (44). The whip antenna (43) passes through the helical antenna (41), and the helical antenna (41) and the whip antenna (43) are electrically insulated from each other. Because the whip antenna (43) is designed to pass through the helical antenna (41), an antenna system for mobile wireless communication can be provided, in which element length is shortened and strength is increased.

摘要： A small-sized wireless device has a whip antenna and a receiver for receiving a call. The whip antenna is provided at the upper side of the rear face of the small-sized wireless device body to improve the antenna performance in a state where a person holds the body to communicate. A rib is provided at a portion of the rear face of the small-sized wireless device body in order to prevent the degradation of the antenna characteristics of the whip antenna at the time of placing the small-sized wireless device body on a metal plate and the like. According to such an arrangement, good sensitivity of the whip antenna can be obtained even when the small-sized wireless device body is placed on a metal plate.
