Title:
ANTENNA DEVICE AND WIRELESS DEVICE
Document Type and Number:
Japanese Patent JP2023000570
Kind Code:
A
Abstract:
To realize an antenna device that can generate a plurality of resonance frequencies.SOLUTION: An antenna device (1) according to an embodiment of the present disclosure includes a ground board (2), a first resonator (3) formed on the ground board (2) and generating a first resonance frequency, and a second resonator (6) having an additional conductor (5) arranged so as to partially overlap the first resonator (3) such that the first resonator (3) is separated by a preset distance in the thickness direction of the ground board (2), and generating a second resonance frequency different from the first resonance frequency with the first resonator (3) and the additional conductor (5).SELECTED DRAWING: Figure 1
