Abstract
A variable type antenna matching circuit includes an antenna, shape change detecting section, transmission/reception radio section, and variable type antenna matching section. The shape change detecting section detects a change in the shape of the housing of a portable terminal. The transmission/reception radio section transmits and receives signals. The variable type antenna matching section changes the input impedance between the antenna and the transmission/reception radio section in accordance with an output signal from the shape change detecting section.
