RADIO−USE ANTENNA DEVICE

摘要

An unbalanced power supply type radio−use antenna device which can be less affected by a human body,improved in gain and reduced in non−absorptance(SAR)without compromise in communication area,and which comprises an antenna element(1)supplied with power and a main plate(3),wherein a platy non−power supply element(7)is disposed along the main plate(3),and the element length of the non−power supply element(7)is set so that the element operates as a reflector when the element(7)is disposed on the human body side and as a wave director when disposed on the opposite side of the human body.
