ANTENNA ELEMENT AND ANTENNA MOUNTING SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To deal with a large change of resonance frequency without changing the basic design of a conductor pattern on a substrate. SOLUTION: A meandering antenna pattern 3 is formed on a substrate 2 serving as a base, and the return points of the antenna pattern 3 are selectively linked so that a return frequency can be adjusted. A conductor pattern 3c on a mother substrate 32 and a conductor pattern 3a on an antenna element 31 are selectively linked through a side through-hole 13c on the side surface of the antenna element 31 so that those conductor patterns can be connected and the meandering antenna pattern 3 can be prepared. The side through-hole 13 is selectively linked so that the return cycle can be adjusted. COPYRIGHT: (C)2005,JPO&NCIPI
