Title: ANTENNA DEVICE
Abstract:
The purpose of the present invention is to reduce the size of an antenna device while ensuring isolation between antennas. An antenna device (1) according to one embodiment of the present invention comprises: a ground conductor (GND1); a first antenna (ANT1); a second antenna (ANT2); and a loop part (LP11). The first antenna (ANT1) and the second antenna (ANT2) are electrically connected to the ground conductor. The loop part (LP11) includes a parasitic element (PE11) and a reactance element (RT11). For the parasitic element (PE11), an end part (T10) is electrically connected to the ground conductor (GND1). For the parasitic element (PE11) an end part (T9) is connected to the ground conductor (GND1) via the reactance element (RT11).
