Abstract
An antenna device and a wireless communication apparatus capable of implementing increase in bandwidth and reduction of the manufacturing cost are provided. The antenna device includes a first antenna element and a second antenna element arranged on one face side of the first antenna element. The first antenna element includes a first glass substrate and a first patch antenna provided on the first glass substrate. The second antenna element includes a second glass substrate and a second patch antenna provided on the second glass substrate. At least part of the first patch antenna faces the second patch antenna with an air gap interposed therebetween.
