摘要： An antenna device includes a ground layer, a first insulating layer, a second insulating layer layered on the ground layer and disposed under a first insulating layer, a patch antenna layered on the first insulating layer for emitting a circularly polarized radio wave, and a parasitic element provided between the first insulating layer and the second insulating layer. The patch antenna includes first and second feed points located in vicinity of a periphery of the patch antenna, which are respectively configured to receive high frequency electrical power having a 90-degree phase difference. The parasitic element is placed in a planar view so as to overlap with at least a part of the periphery of the patch antenna close to the first feed point and the second feed point.
