ANTENNA APPARATUS AND WRISTWATCH RADIO COMMUNICATION DEVICE USING SAME

摘要

An antenna apparatus for use in a wristwatch radio communication device equipped with, for example, a PHS is provided. The antenna apparatus includes a loop conductor and a feed. The loop conductor has a given length and connects electrically at one end to a ground plate installed in the wristwatch radio communication device. The feed is disposed between the other end of the loop conductor and the ground plate. This provides a higher horizontal pattern average gain both during conversation and waiting times of radio communication.
