Title:
ANTENNA DEVICE, ANTENNA MODULE, AND COMMUNICATION TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/002423
Kind Code:
A1
Abstract:
An antenna device is provided with: an antenna coil (10) having a first end and a second end; and an IC (20) having at least a first terminal and a second terminal. When the antenna device is installed on a circuit board (40) and is connected to a conductor pattern formed on the circuit board (40), a plurality of external terminals (T1, T2) are provided which form a closed loop together with the antenna coil (10) and the IC (20). For example, a linear conductor pattern (41) connects the external terminals (T1, T2). The antenna device and an antenna module, which are less likely to malfunction before being incorporated into electronic equipment, are thus formed, and a communication terminal device provided therewith is also formed.
