<p>PURPOSE: A multi-band built-in antenna having a dual feeding structure is provided to secure isolation between a low-frequency radiation part and a high-frequency radiation part by forming a plurality of parallel feeding lines in parallel to each other. CONSTITUTION: A low-frequency radiation part(300) is operated in a low-frequency band. A high-frequency radiation part(400) is operated in a high-frequency band higher than the low-frequency band part. The low-frequency radiation part and the high-frequency radiation part are formed as the predetermined conductive patterns. A feeding part(100) supplies feeding signals to the low-frequency radiation part and the high-frequency radiation part. A grounding part(200) is arranged adjacently to the feeding part.</p> |
