The signal transmission apparatus includes: a first sheet conductive body portion constituting a lower portion electrode; and a second sheet conductive body portion in a mesh shape which is laminated on the first sheet conductive body portion while a gap area is sandwiched therebetween and which includes an uneven mesh size area on which a sheet impedance is continuously changed. | 06-21-2012 |
20130015926 | NOISE SUPPRESSION STRUCTUREAANM Nakase; KoichiroAACI TokyoAACO JPAAGP Nakase; Koichiro Tokyo JPAANM Hankui; EijiAACI TokyoAACO JPAAGP Hankui; Eiji Tokyo JP - 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. | 01-17-2013 |
