Abstract
An antenna stack structure according to an embodiment includes a lower dielectric layer, an antenna electrode layer formed on the lower dielectric layer, and an upper dielectric layer disposed on the antenna electrode layer. A dielectric constant of the upper dielectric layer is 1 or more and less than 7, and a thickness of the upper dielectric layer is in a range from 100 μm to 1,300 μm. A frequency and a band width are finely controlled using the upper dielectric layer while suppressing excessive gain reduction and frequency shift.
