Abstract:
An impedance converter for an antenna includes a first port receiving a power from an antenna driving integrated circuit, an impedance modulator connected to the first port to convert an impedance, and a second port connected to the modulator and configured to perform a feeding to an antenna unit. The second port has an impedance higher than that of the first port. Impedance mismatching is prevented by the impedance modulator to improve antenna properties.
