More Information
Summary:An antenna apparatus includes: a first dielectric layer having a first dielectric constant; a first patch antenna pattern disposed in the first dielectric layer; a second dielectric layer having a second dielectric constant; a second patch antenna pattern disposed on the second dielectric layer; a first feed via coupled to the first patch antenna pattern; and a second feed via coupled to the second patch antenna pattern. The first dielectric constant is higher than the second dielectric constant, and a frequency of a signal transmitted/received by the first patch antenna pattern is lower than a frequency of a signal transmitted/received by the second patch antenna pattern.
