摘要： A combined antenna combining a circularly polarized wave antenna and a vertically polarized wave antenna is provided. A flat plate antenna for ground waves is fixed on a printed board, and a two-point feeding type patch antenna is placed and fixed on a metallic flat plate of the plate antenna. The plate antenna has one feed terminal and six uniformly spaced ground terminals. The patch antenna has two feed pins at equidistant positions from the center of the patch electrode along radial lines that form a right angle. Each of feed pins is connected to a 90-degree phase difference circuit using an opening of the plate antenna. The relative position between the flat plate and the patch electrode is the same along the peripheral direction. All of the feed terminals, the ground terminals and the feed pins have a predetermined positional relationship relative to one another.

摘要： In an antenna structure having a transmit antenna disposed over a first section of a ground plane and a receive antenna disposed over a second section of the ground plane, a cut is provided between the first and second sections of the ground plane. The length of the cut is substantially equal to one quarter-wavelength of the operating frequency band of transmit/receive antenna pair so as to provide isolation between the transmit antenna and the receive antenna. If the antenna structure also has a transceiver antenna operated in a further frequency band disposed over the same ground plane and straddling over the first section and the second section, a switch is provided over the cut. The switch is operating in a closed position when the transceiver antenna in the further frequency band is used, and in an open position when the transmit/receiver antenna pair is used.

摘要： A fractal structure is formed to have a plurality of regions different in fractal dimension characterizing the self-similarity. Especially in a stellar fractal structure, a region with a low fractal dimension is formed around a core with a high fractal dimension. By adjusting the ratios in volume of these regions relative to the entire fractal structure, the nature of phase transition occurring in the fractal structure, such as a magnetization curve of Mott transition or ferromagnetic phase transition, quantum chaos in the electron state, or the like. For enhancing the controllability, the fractal dimension of the core is preferably larger than 2.7 and the fractal dimension of the region around the core is preferably smaller than 2.3.

摘要： An antenna (10) having a plurality of unitary dipole antennas (12) formed by folding a stamped piece of sheet metal. Each of the unitary dipole antennas (12) are fed by two stripline feed systems (20, 22). Each of these feed systems are separated above and extend over a groundplane (14) and are separated by an air dielectric to minimize intermodulation (IM). Phase shifters (40, 42, 44) in combination with a downtilt control lever (52) are slidably adjusted beneath the respective dividing portions of the stripline feed system to adjust signal phase and achieve a uniform beam tilt having uniform and balanced side lobes. These stripline feed systems can also be formed from stamped sheet metal and which have distal ends bent 90null upward to couple to the respective dipole antennas (12).

摘要： There will be provided a plane patch antenna through which a desired resonance frequency can be obtained with stability without requiring any troublesome frequency adjusting operation. On one surface of a dielectric substrate to be obtained by calcining ceramic powder press-molded in a desired shape, a concave groove is continuously formed along the inside of its outer edge, and on an entire surface within a region partitioned by this concave groove, a patch electrode is thick-film printed. In the plane patch antenna structured as described above, the precision of the patch electrode during thick-film printing becomes excellent depending upon the processing precision of the concave groove, and yet, a fluctuation in a resonance frequency associated with variations in a dielectric constant and a fluctuation in the resonance frequency associated with variations in the area of the patch electrode offset each other, and therefore, a desired resonance frequency can be obtained with stability irrespective of the variations in dimension of the dielectric substrate after calcination.
