Abstract
A communication terminal in which a card antenna module is loaded into a terminal casing including an antenna is operated such that a degree of coupling between a terminal-casing-side antenna and a module-side antenna is minimized and that a module-side antenna has a desired frequency characteristic. The communication terminal includes a terminal casing including a terminal-casing-side antenna, and a card antenna module loaded into the terminal casing. The card antenna module includes a coupling coil which is disposed at a position close to the terminal-casing-side antenna and which is coupled with the terminal-casing-side antenna via a magnetic field, and a module-side antenna which is disposed at a position more distant from the terminal-casing-side antenna than the coupling coil.
