1. An antenna comprising:
a first insulating layer;
a second insulating layer disposed on the first insulating layer in a height direction;
a third insulating layer disposed between the first insulating layer and the second insulating layer;
a feed via comprising a first portion passing through the first insulating layer, a second portion passing through the second insulating layer, and a third portion passing through the third insulating layer and connected to the first portion and the second portion; and
an antenna patch disposed on the second insulating layer and fed from the feed via,
wherein a permittivity of the third insulating layer is lower than a permittivity of the first insulating layer and a permittivity of the second insulating layer, and
in a direction perpendicular to the height direction, a width of the third portion of the feed via is wider than either one or both of a width of the first portion of the feed via and a width of the second portion of the feed via.
