YAGI ANTENNA CAPABLE OF REDUCING OWN HEIGHT TO A HALF BY FORMING ON A RADIATOR, A REFLECTOR, AND A DIRECTOR ON THE GROUND

摘要

PURPOSE: A yagi antenna is provided to cover broadband by forming a sleeve around a director which is the element of the yagi antenna. CONSTITUTION: A ground plane(310) is comprised of a predetermined conductor plate. A radiator(320) radiates a radiation signal by receiving a certain frequency signal. A reflector(330) reflects the radiation signal. A director(340) makes the radiation signal larger. The directors are arranged on the one side of the radiator at certain interval.
