MULTI BAND ANTENNA USING THE HETEROGENEOUS DIELECTRIC SUBSTANCES

摘要

A multi-band antenna using heterogeneous dielectrics is provided to improve characteristics of the antenna by operating first and second radiators in specific frequency bands respectively in correspondence to first and second dielectrics. A multi-band antenna using heterogeneous dielectrics includes a first dielectric(100), a second dielectric(200), a radiator(300), and a feed unit(400). The first dielectric has a low dielectric constant. The second dielectric has a high dielectric constant and is coupled with the first dielectric. The radiator is formed in a folded line type single pattern on the first and second dielectrics. The feed unit is connected to one side of the radiator to feed signals. The radiator is composed of a first radiator formed on the first dielectric and a second radiator formed on the second dielectric.
