    摘要: Disclosed is a wideband antenna with a lowered standing wave ratio. The wideband antenna interposes a substance whose conductivity is about 0.1 through 10.0 as an interposition between a reference conductor and a radiation conductor; and thereby, the antenna reduces reflections of signals, and achieves a wider bandwidth as well as a sufficient gain with a lowered standing wave ratio. Also, the invention realizes a thin-type wideband antenna with a wider bandwidth and a sufficient gain, by interposing a magnetic substance whose relative permeability is more than 1 through about 8 as the interposition between the reference conductor and the radiation conductor.

    摘要: Disclosed is a wideband antenna with a lowered standing wave ratio. The wideband antenna interposes a substance whose conductivity is about 0.1 through 10.0 as an interposition between a conductive plate and a radiation conductor; and thereby, the antenna reduces reflections of signals, and achieves a wider bandwidth as well as a sufficient gain with a lowered standing wave ratio. Also, the invention realizes a thin-type wideband antenna with a wider bandwidth and a sufficient gain, by interposing a magnetic substance whose relative permeability is more than 1 through about 8 as the interposition between the conductive plate and the radiation conductor.

    摘要: The present invention is to provide each communication station with a transmission prioritised period without any useless latency in an ad-hoc communication environment including no control station. For this end, each communication station periodically transmits the beacon signal and acquires the transmission prioritised period immediately after transmission of the beacon. If the number of communication stations in the network is small, a communication station transmit a supplementary beacon within the super frame period, thereby effectively shortening the beacon interval and reducing latency at the start of transmission. At the time when a new communication station enters the network, the supplementary beacon is released in order to accommodate such new communication station.

    摘要: A cellular wireless communication system for further improving the quality of communications. The base station (BS11) notifies the communication channel which the mobile station (MS10) is using, to the base stations (BS12, BS13) having the lower pathloss than the own station, the base stations receive said communication channel and transmit the reception signals (S2, S3) to the connection switching station (11), and the connection switching station combines respective reception signals (S1-S3) to be transmitted so as to restore the data transmitted from the mobile station, and thereby the reception signal received at the base station having the satisfactory receiving condition can be combined and the diversity reception using the whole system can be conducted, so that the quality of communications from the mobile station to the base station can be easily improved.
