COIL STRUCTURE AND ELECTRONIC APPARATUS

Japanese Patent JP2014160704

A

PROBLEM TO BE SOLVED: To properly ensure desired impedance characteristics in a wide-range frequency band.SOLUTION: A coil structure 1 includes: a plurality of core members 2 having different frequency characteristics of impedances from each other; and a winding member 3 wounded around the plurality of core members 2. The plurality of core members 2 includes an Mn-Zn-based first core member 2a and a Ni-Zn-based second core member 2b that are independent from each other. The first core member 2a and the second core member 2b have an annular shape. The winding member 3 is sequentially wound around the plurality of core members 2 and is spirally wound in the same direction so as to proceed in the circumferential direction of the core members 2. The winding member 3 is a coaxial cable and includes a core wire composed of a conductor, an insulating layer composed of a dielectric and covering the core wire, and a shield braided wire composed of a conductor and covering the insulating layer.
