Study of compact and broad spectrum coil by the laminated substrates structure

Abstract

We develop compact and broad spectrum coil for application of the current sensor. We propose the laminated substrates type coil using PALAP (Patterned prepreg Lay up Process) substrates excellent in high frequency characteristics and miniaturization, and we verify that frequency band of 1.2GHz and thickness of 0.7mm could achieve with a prototype.
