PHASE CONTROLLED LOOP ANTENNA

摘要

A phase controlled loop antenna is provided to increase a radiation characteristic efficiency of an electromagnetic field by adjusting directions of adjacent loop patterns in a reverse direction which forms the electromagnetic field of sync phase between adjacent loop patterns. A phase controlled loop antenna includes a dielectric substrate or dielectric film(30) for forming a loop antenna pattern, first and second loop patterns(31,32) formed in a flow direction of an electric current and a return direction of the electric current and each having a width w and a width d, and third and fourth loop patterns(33,34) formed in a flow direction of the electric current and a return direction of the electric current. The first to fourth loop patterns form plural patterns continuously.
