Abstract:
The present invention comprises: a first conductor section (1) being a radiation element for a standing wave antenna for a first frequency band and having connected thereto a first power supply circuit (91) for the first frequency band; and a linear conductor (20) partially or fully formed on a circuit board and connected to at least two locations (P1, P2) on the first conductor section (1). In addition, a loop section for a second frequency band field antenna has a second frequency band second power supply circuit (92) connected thereto and is formed by part of the first conductor section (1) and by the linear conductor (20). The opening width W2 in the loop section is larger than the length W1 of the radiation element (1) between the connection locations (P1, P2) for the radiation element.
