摘要：Radiation electrodes are formed on a dielectric base body of an antenna chip. Acapacitive feeding electrode is formed on a first end surface of the dielectric base body.A ground electrode, a feeding circuit connection electrode, feeding lines, a tip electrode,

and the like are formed on the top surface of a base member of a substrate. When a firstswitching element selects the feeding line side, a second switching element is made toenter a conducting state. In this state, the radiation electrodes are capacitively fed. Whenthe first switching element selects the feeding line side, the second switching element ismade to enter an open state. In this state, the radiation electrodes are directly fed. Inthis manner, the directivity direction of an antenna can be switched using a singleradiation element.
