Abstract
An antenna module and a portable communication terminal equipped with the antenna module are provided. The antenna module has a space-saving design, and also has both a capability for long communication distance for a tag function and a capability for wide communication range for a reader/writer function. A first antenna coil () for communication with a reader/writer and a second antenna coil () for communication with an IC tag are disposed on a base substrate (). The first antenna coil () is disposed in an outermost periphery section of the base substrate () so that a communication distance is attained. The second antenna coil () is disposed within an inner periphery of the first antenna coil () so as to achieve overall size reduction of the module.
