Title:
ANTENNA DEVICE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/193793
Kind Code:
A1
Abstract:
This antenna device (10) comprises: a first conductor layer (20); a second conductor layer (30) placed opposing the first conductor layer (20); and a third conductor layer (40) placed opposing the second conductor layer (30). The first conductor layer (20) has: a power feeding element (21); a first grounding element (22) that is placed at a position adjacent in a first direction to the power feeding element (21), and is grounded; and a parasitic element (23) that is placed along the power feeding element (21) and the first grounding element (22), and insulates the power feeding element (21) and the first grounding element (22). The second conductor layer (30) has: a floating element (31) that is placed opposing the power feeding element (21) and is insulated from the first conductor layer (20); and a second grounding element (32) that is placed opposing the first grounding element (22) and at a position adjacent to the floating element (31), and is grounded. The third conductor layer (40) has a third grounding element (41) that is grounded.
