Abstract
A noise suppression structure for suppressing an undesired high-frequency current in a transmission line (i.e. a sleeve) of a short-circuited termination type includes a conductor base encompassing the periphery of the transmission line and a conductor short-circuiting part which is connected to the transmission line at the opposite side to an open end of the conductor base and whose inductance is greater than that of the conductor base. It is possible to increase an inductance by modifying the shape of the terminal end of the sleeve, equivalent to a quarter wavelength of an undesired high-frequency current which occurs in a wireless circuit of a mobile wireless terminal and flows through a ground layer, thus reducing the entire length and realizing miniaturization while securing desired input impedance.
