High efficiency antennas of reduced size on dielectric substrate |
摘要 |
An antenna formed on a dielectric substrate including at least a first and second dielectric substrate region. One or more antenna-radiating element is formed on the first region of the dielectric substrate and defines a conductive path. Feed circuitry for the antenna can be formed on the second region of the dielectric substrate. The feed circuitry can comprise a balun, an impedance transformer, and/or a feed line. The dielectric substrate in the first region can preferably have a first relative permeability and/or first permittivity different from a second relative permeability and/or a second permittivity of the dielectric substrate of the second region.
