Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/198970
Kind Code:
A1
Abstract:
This antenna device comprises: a dielectric substrate (2); a ground plate (3); an antenna section (4); and an added-function section (5). The dielectric substrate includes a plurality of pattern forming layers. The ground plate is formed on a first pattern forming layer among the plurality of pattern forming layers, and functions as an antenna ground surface. The antenna section is formed on a pattern forming layer different from the first pattern forming layer among the plurality of pattern forming layers, and includes one or more antenna patterns configured to function as a radiator element. The added-function section includes one or more non-feed patterns (51) disposed on a propagation path for an acoustic wave propagating on the dielectric substrate, and causes a radiation wave to be generated using the acoustic wave, the radiation wave having a polarization different from that of radio waves transmitted and received by the antenna section.
