20090251380DUAL POLARIZED ANTENNA - To provide a dual polarized antenna capable of reducing correlation between antenna elements.10-08-2009
20090303136ANTENNA DEVICE AND COMMUNICATION DEVICE USING THE SAME - An antenna device which is very compact, low in profile, wide in bandwidth, simple in configuration and inexpensive is provided. A plate type wideband antenna device according to the present invention is formed with a radiation element which is formed by bending a tapered conductor plate 12-10-2009
20100026586PLANAR ANTENNA, AND COMMUNICATION DEVICE AND CARD-TYPE TERMINAL USING THE ANTENNA - There are provided a planar antenna that reduces interactions between an antenna section and a peripheral circuit section on each other's electric operations in an apparatus in which an antenna and a peripheral circuit are arranged together on a printed circuit board, and a communication device and a card-type terminal that use the planar antenna. The planar antenna has the antenna section and the peripheral circuit section which are arranged on the printed circuit board. The planar antenna includes: on one surface of the printed circuit board, a plate element that constitutes the antenna section, a microstrip line that is connected with the plate element and feeds electricity from a peripheral circuit to the plate element, and a peripheral circuit mounting area in which the peripheral circuit section is arranged; and, on the other surface of the printed circuit board, a first ground portion that constitutes a ground-side conductor of the peripheral circuit section, and a second ground portion that constitutes a ground-side conductor of the microstrip line. The second ground portion is arranged on the printed circuit board other than the first ground portion. The connection between the plate element and the microstrip line is located on the side of the second ground portion away from the first ground portion.02-04-2010
20100231477SMALL-SIZE WIDE BAND ANTENNA AND RADIO COMMUNICATION DEVICE - A small-size wide-band antenna (09-16-2010
20100321273WIDEBAND ANTENNA AND CLOTHING AND ARTICLES USING THE SAME - Provided are a first planar radiating element and second planar radiating element that have at least one side. At least the first or second radiating element has a strip-shaped element. A first side of the first radiating element and a second side of the second radiating element are so disposed as to be parallel to each other, face each other and be shifted slightly in a parallel direction. The strip-shaped element is so disposed as to be connected to any side other than the first and second sides of the first and second radiating elements, run parallel to the first and second sides, and not go beyond tips positioned at the outermost points of the first and second sides.12-23-2010
20110140976ARTICLE STORAGE APPLIANCE AND CONNECTING METHOD - An object is to provide a goods storage tool that enables an antenna to be connected to an electronics device without the need to take out the antenna from a storage object in which the antenna is stored. A goods storage tool of the present invention is a goods storage tool for storing goods or contents therein. The goods storage tool includes an antenna that is stored in the goods storage tool; and a connection portion that enables a feeder connector connected to an electronics device to be connected to the antenna in such a way that the antenna remains stored in the goods storage tool.06-16-2011

20100007573MULTIBEAM ANTENNA - An antenna having two beams low in correlation and effective for MIMO is provided.01-14-2010
20100090787FEED DEVICE - There is provided a less fragile feeding apparatus for an antenna that can be fitted to clothing. The feeding apparatus uses a coaxial cable for feeding. A center conductor of the coaxial cable is connected to a first radiating element in terms of alternating current at least through capacitive coupling, and an outer conductor of the coaxial cable is connected to a second radiating element in terms of alternating current at least through capacitive coupling.04-15-2010
20100141541WIDEBAND ANTENNA - A wideband antenna includes a first radiating element and a second radiating element which are substantially in the same shape of a flat plate. A first side of the first radiating element is parallel to a second side of the second radiating element. Moreover, the first and second radiating elements are so arranged as to be shifted from each other with part of the first side facing part of the second side. If the first and second radiating elements thus arranged are moved in parallel so that the first and second sides face each other and are parallel to each other, the first and second sides substantially have line symmetry.06-10-2010
