Abstract
A chip antenna includes a first substrate, a second substrate overlapping the first substrate, a first patch, provided on a first surface of the first substrate, operating as a feed patch, a second patch, provided on the second substrate, operating as a radiation patch, at least one feed via penetrating through the first substrate in a thickness direction and configured to provide a feed signal to the first patch, and a ground pad provided on the other surface of the first substrate. The first substrate comprises a ceramic sintered material. The ceramic sintered material comprises an MgSiOphase, an MgAlOphase, and a CaTiOphase, and a content of the CaTiOphase in the ceramic sintered material ranges from 5.1 mol % to 15.1 mol %.
