多周波共用アンテナ及びアンテナの複数周波数帯での使用方法

摘要

PROBLEM TO BE SOLVED: To provide a multi-frequency common antenna capable of commonly using a power feeding unit at a plurality of frequencies with a simple configuration.;SOLUTION: A multi-frequency common antenna comprises a plate, a first conductor, a second conductor, a current path switching unit, and a power feeding unit. The plate is composed of a dielectric. The first conductor is arranged on one side surface in a thickness direction of the plate. The second conductor is arranged on the other side surface in the thickness direction of the plate, and includes a notch in an outer periphery of the conductor. The current path switching unit connects second conductors so as to straddle the notch, and can switch passage and blocking of current according to a radio wave frequency. The power feeding unit electrically connects the second conductor and a feeder line.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
