摘要： A patch having a circular shape for instance is formed on the main surface of a substrate in the shape of, for example, an equilateral triangle. The center of the main surface of the patch is at a position different from the center of the substrate. A grounding conductor is disposed on the backside of the substrate. Power is supplied to the patch through, for example, a microstrip line, triplate line, coplanar waveguide, slot line or the like. An antenna configured as described above has the center of the patch at a position different from the center of the triangle substrate, so that beams can be tilted in a desired direction by a single patch and a single feeder circuit.

摘要： An antenna apparatus is constituted by first, second, third, and fourth wire antenna elements and a connection element. The sum of the lengths of the first, second, and fourth wire antenna elements is ¼ the wavelength corresponding to a series-resonance frequency of the first, second, and fourth wire antenna elements. The sum of the lengths of the second, third, and fourth wire antenna elements is ½ the wavelength corresponding to a parallel-resonance frequency of the second, third, and fourth wire antenna elements. The sum of the lengths of the first and third wire antenna elements is ¼ the wavelength corresponding to a series-resonance frequency of the first and third wire antenna elements. The parallel-resonance frequency is higher than the series-resonance frequency of the first, second, and fourth wire antenna elements and lower than the series-resonance frequency of the first and third wire antenna elements.

摘要： There is disclosed a radio communication system in which a constitution of a base station and further a control station can be simplified. A radio communication system according to the present invention converts a received signal received by a plurality of antenna elements in a base station to a signal of different frequency band, and then conflates the converted signal in order to generate sub-carrier wave multiplex signal. The signal is converted to an optical signal, and then the optical signal is transmitted to a control station via an optical fiber. Or the control station performs weighting to phase of the transmitted signal transmitted from a plurality of antennas of a base station, and then performs frequency conversion to different frequency band, and then conflates the converted signal in order to generate the sub-carrier wave multiplex signal. The signal is converted to an optical signal, and then an optical signal is transmitted to the base station side via the optical fiber. The control station and the base station divides the received sub-carrier wave multiplex signal by each frequency band, and then the frequency of the divided signals are converted to the same frequency band in order to generate the transmitted/received signal of each antenna element. By such a constitution, it is possible to reduce constituent of the optical transmission components to the minimum and to simplify the constitution of the base station. Furthermore, it is possible to maintain the relative phase difference and the relative intensity of the transmitted/received signal of each antenna element. Because of this, it is possible to estimate an arrival direction of the received signal and to control radiation beam pattern of the transmitted signal.
