Antenna built in mobile terminal

摘要

An antenna built in a mobile phone that includes a front case having, on its surface, an operation portion and a rear case arranged on the rear of the front case is provided. The antenna includes a bar-shaped support member that is made of a synthetic resin and is located in the rear case along an upper side of the inside surface thereof, an antenna element integrally formed with the support member, and a concave portion provided in the support member to avoid interfering with a strap retaining portion that projects into the rear case at the center of the upper side of the rear case. The antenna element is formed in such a manner that the antenna element straddles a gap between edge portions of both side walls of the concave portion to avoid interfering with the strap retaining portion.
