Antenna structure and mobile terminal having antenna structure

摘要

A flexible substrate having a meandering antenna element (119) and a matching circuit (120) formed thereon is wound within an antenna cap (110) and mounted on a terminal body (10). A rod-like antenna (122) is arranged extensible within the flexible substrate. If the rod-like antenna (122) is withdrawn, a linear antenna element (123) is coupled by a capacitive coupling with the matching circuit (120) formed on the flexible substrate. Also, if the rod-like antenna (122) is returned into the terminal body (10), the capacitive coupling between the linear antenna element (123) and the matching circuit (120) is released, and the meandering antenna element (119) is coupled by a capacitive coupling with the matching circuit (120) on the flexible substrate. <IMAGE>
