| 20100231453 | ARRAY ANTENNA APPARATUS INCLUDING MULTIPLE STEERABLE ANTENNAS AND CAPABLE OF AVOIDING AFFECTION AMONG STEERABLE ANTENNAS - A steerable antenna includes an radiating antenna element and parasitic antenna elements. Each of the parasitic antenna elements is provided with a pair of PIN diodes. On each of control lines connecting the PIN diodes to a controller, inductors are provided at predetermined intervals on portions of the control line electromagnetically coupled to another steerable antenna. The intervals for providing the inductors is set to such a length that substantially no resonance occurs in a section of the control line between the inductors at an operating frequency of the steerable antenna. | 09-16-2010 |
| 20100246496 | WIRELESS COMMUNICATION SYSTEM HAVING MIMO COMMUNICATION CAPABILITY AND HAVING MULTIPLE RECEIVING ANTENNAS TO BE SELECTED - Before start of streaming, a server apparatus obtains from client apparatuses their respective numbers of antenna combinations, determines a training time t | 09-30-2010 |
| 20110065391 | WIRELESS COMMUNICATION APPARATUS FOR CHANGING DIRECTIONAL PATTERN OF VARIABLE DIRECTIVITY ANTENNA ACCORDING TO VARIATIONS IN RADIO WAVE PROPAGATION ENVIROMENT - When a variable directivity antenna apparatus is controlled to form an initial composite directional pattern, RSSI is measured, and a weak electric field group or an intense electric field group is selected based on the measured RSSI. When the variable directivity antenna apparatus is controlled to form the composite directional patterns included in the selected composite directional pattern group, PER for each of the composite directional patterns is measured, and one composite directional pattern is selected from among the composite directional patterns included in the selected composite directional pattern group based on the measured PER, so that the variable directivity antenna apparatus is controlled to form the selected composite directional pattern. | 03-17-2011 |
| 20110102287 | VARIABLE DIRECTIVITY ANTENNA APPARATUS PROVIDED WITH ANTENNA ELEMENTS AND AT LEAST ONE PARASITIC ELEMENT CONNECTED TO GROUND VIA CONTROLLED SWITCH - A variable directivity antenna apparatus is configured to include a parasitic element, a plurality of antenna elements each provided to be away from the parasitic element by an electrical length of a quarter-wavelength, and a | 05-05-2011 |
| 20110143698 | DIRECTIONAL PATTERN DETERMINING METHOD CAPABLE OF QUICKLY SELECTING OPTIMUM DIRECTIONAL PATTERN - A plurality of directional patterns are classified into groups and stored in a directional pattern memory, such that among the plurality of directional patterns, the directional patterns strongly correlated with each other are classified into the same group, while the directional patterns weakly correlated with each other are classified into the different groups. One directional pattern is selected from each group in the directional pattern memory. One directional pattern is determined from the selected directional patterns, in accordance with a communication quality of signals each received when each one of the selected directional patterns is set for steerable antenna element. The determined directional pattern is set for the steerable antenna element. | 06-16-2011 |
| 20110193761 | ANTENNA APPARATUS INCLUDING FEEDING ELEMENTS AND PARASITIC ELEMENTS ACTIVATED AS REFLECTORS - An antenna apparatus includes an antenna element and a parasitic element provided on a first surface of a dielectric substrate, and an antenna element and a parasitic element provided on a second surface of the dielectric substrate. Each of the parasitic elements is provided at a position away from the antenna elements by a distance of one-fourth of an operating wavelength λ in communication. | 08-11-2011 |
