SECTOR ANTENNA FOR WIDE BAND MOBILE COMMUNICATION

摘要

PURPOSE: A sector antenna for a broadband mobile communication is provided to supply a high speed data image service by providing a broadband service with 30 to 40% of a center frequency. CONSTITUTION: A reflector(102) is made of metal. A radiator is attached to the front of the reflector at a vertical direction, a horizontal direction, a -45 degrees direction or a +45 degrees direction. A broadband radiator includes the radiator which is vertically arranged with N stages. A distributer(110) distributes a feeding signal with multi stages and provides the broadband radiator. The broadband radiator resonates at a high frequency or center frequency.
