摘要： A portable wireless device realizing high-speed transmission in downlink communication in a used state that a foldable portable wireless device is held in a hand of the user and ensuring a high antenna radiation efficiency. In the portable wireless device, platy conductors (1, 3, 4) are arranged in the longitudinal direction on the back of a display section (35) of an upper case (5). The signal of a transmission circuit (25) is distributed by a power distributor (18). One signal is fed to a platy conductor (1) through a phase shifter (17) and the other is fed to the platy conductor (3) or the platy conductor (4) from a high-frequency switch (19) through a transmission/reception duplexer (20) or a transmission/reception duplexer (21). The high-frequency switch (19) selectively feeds power to either the platy conductor (3) or the platy conductor (4) according to the signal from a gravity sensor (26). The received signal is extracted by the transmission/reception duplexers (20, 21), amplified by a receiving circuit (22) and a receiving circuit (23), and multiplied by a predetermined weight coefficient by a demodulating section (24) and combined.

In the mobile telephone, a helical antenna (4) operating as an antenna for television reception is formed by winding a conductive element along the external surface of the case several times at the upper end of the upper case (1). The helical antenna (4) is impedance-matched by a matching circuit (5) in a range of the order from 470 MHz to 700 MHz which is the television broadcast frequency. The matching circuit (5) is connected to a broadcast reception circuit (6). The broadcast reception circuit (6) operates as a reception circuit for receiving the television broadcast wave.

摘要： A portable wireless unit capable of ensuring high speed, large capacity communication by lowering the correlation coefficient between antennas under various use states of a user. An antenna element (1) is arranged outside from the upper end of a case (4) on the side opposite to the display section (23) of the case, an antenna element (2) is arranged in parallel with and on the same side of the antenna element (1) while spaced apart in the width direction, and an antenna element (3) is arranged in parallel with the antenna element (1) from the display section (23) side spaced apart from the antenna element (1) in the thickness direction. The antenna element (1) is connected with a transmitter/receiver (14), and any one of the antenna element (2) or (3) is selected by controlling a high frequency switch (11) by angle information from a gravity sensor (22) and connected with the transmitter/receiver (14).
