20090231215 | SLOT ANTENNA AND PORTABLE WIRELESS TERMINAL - A slot antenna is provided with at least two conductive plates arranged to face each other. A slot is arranged on one of or both of the facing conductive plates and has a long and narrow opening shape. A power feeding unit is arranged between the facing conductive plates and is electrically and physically connected with the facing conductive plates, respectively. When power is fed to the power feeding unit, the power is fed between the facing conductive plates by the power feeding unit. Thus, excitation with a frequency dependent on the electrical length of the slot is induced at the slot, and a current excited at the slot is distributed entirely over one conductive plate, the current becomes a radiation source, and an electromagnetic wave is radiated from the one conductive plate. At this time, the other conductive plate operates as the reflecting plate of the electromagnetic wave. | 09-17-2009 |
20090233546 | TRANSMISSION METHOD, INTERFACE CIRCUIT, SEMICONDUCTOR DEVICE, SEMICONDUCTOR PACKAGE, SEMICONDUCTOR MODULE AND MEMORY MODULE - An interface circuit, which uses electromagnetic induction to perform a signal transmission, comprises a transmission coil and a transmission circuit that provides a signal to the transmission coil, thereby causing the transmission coil to output a triangular or roughly triangular magnetic field signal. | 09-17-2009 |
20100207835 | SLOT ANTENNA - To make an antenna wideband under thin state. The slot antenna includes an antenna element having an aperture type slot, a reflector disposed by opposing to the antenna element, a feeding device which is electrically and physically connected to the antenna element and the reflector, a short-circuiting device which electrically short-circuits the antenna element and the reflector, and a reducing device which reduces the reactance component of the antenna. Since the reducing device for reducing the reactance component of the antenna is provided, the reactance component of the antenna can be reduced even if the antenna is formed thin and the antenna can be made wideband regardless of its thinness. | 08-19-2010 |
20100225544 | SLOT ANTENNA AND PORTABLE WIRELESS TERMINAL - To provide a portable wireless terminal having a reduced thickness and fine antenna performance. A slot antenna is provided with an antenna element having an aperture silt shaped slot; a reflection plate disposed by being opposed to the antenna element; and a power feeding device which is electrically and physically connected to the antenna element and the reflection plate. The slot antenna has a structure wherein an opening end of the slot and an end of the reflection plate are shifted from each other. Since only the antenna element and the reflection plate opposing to each other are disposed in the thickness direction (vertical direction) of the antenna, the size in the thickness direction of the antenna can be reduced. Further, through controlling the reactance component of the antenna, the characteristic of a transmitting/receiving antenna can be improved. | 09-09-2010 |
