CHIP ANTENNA HAVING A MAGNETIC SUBSTRATE

摘要

PURPOSE: A chip antenna including a magnetic substrate is provided to prevent a noise by forming an antenna pattern in a printing method on a magnetic substrate. CONSTITUTION: A magnetic substrate (10) has a first side and a second side facing each other. An antenna pattern (20) comprises a spiral pattern, a first penetration pattern, and an extension pattern. The spiral pattern has an inner end part and an outer end part. The first penetration pattern penetrates through the magnetic substrate. First and second input-output terminals (32, 34) are connected electrically with the antenna pattern.
