ANTENNA INCLUDING RESONATOR

摘要

PURPOSE: An antenna integrated with a resonator is provided to improve phase center variation and a gain in a low angle of elevation by integrating the antenna with the resonator. CONSTITUTION: A conductive line(201) is electrically connected to an internal circuit. At least one spiral coil(202,203) is fed from a conductive line. A matching unit(401,402) performs impedance matching between the conductive line and the spiral coil. An absorbing unit(403) is formed along the conductive line to reduce the reflection loss of the antenna. A resonator(204) partially or entirely surrounds the external side of the spiral coil.
