ANTENNA FOR CIRCULAR-POLARIZED WAVE, INCLUDING LINEAR CONDUCTOR ARRANGED TO FORM SINGLE PLANE, AND INTEGRATED ANTENNA HAVING THE SAME

摘要

PURPOSE: An antenna for a circular-polarized wave and an integrated antenna are provided to reduce the thickness of the antenna and permit the antenna to be mounted on a vehicle by arranging a linear conductor of the antenna so as to form a single plane. CONSTITUTION: An antenna(10) for a circular-polarized wave, comprises an antenna for a linear-polarized wave, having an antenna conductor for transmitting and/or receiving the linear-polarized wave; and a passive element arranged around the antenna conductor of the antenna for a linear polarized wave, and constituted by a conductor independent from the antenna conductor.
