Abstract
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 () are arranged in the longitudinal direction on the back of a display section () of an upper case (). The signal of a transmission circuit () is distributed by a power distributor (). One signal is fed to a platy conductor () through a phase shifter () and the other is fed to the platy conductor () or the platy conductor () from a high-frequency switch () through a transmission/reception duplexer () or a transmission/reception duplexer (). The high-frequency switch () selectively feeds power to either the platy conductor () or the platy conductor () according to the signal from a gravity sensor (). The received signal is extracted by the transmission/reception duplexers (), amplified by a receiving circuit () and a receiving circuit (), and multiplied by a predetermined weight coefficient by a demodulating section () and combined.
