摘要： A low and broadband shorted microstrip antenna is disclosed which is mainly applicable to a mobile body in a mobile communication system. A first grounding conductive sheet which faces a radiating conductive sheet is provided at both ends thereof with a second and a third grounding conductive sheets which are perpendicular to the first grounding conductive sheet, whereby a beam tilt characteristic of the antenna is improved. The passive element and a conductive stub are disposed atop the grounding conductive sheet. The passive element and the conductive stub face the radiating conductive element and serve to improve the impedance matching parameter of the microstrip antenna.

摘要： Input is applied to a two-partition circuit that substantially equally distributes input power into two partitions having a phase difference of 90.degree., and the thus-distributed output is applied to a first driver that generates circularly polarized wave. The two outputs of the second driver, in which the circularly polarized waves generated from the first driver are coupled, are combined in a combining circuit. The end portion of the opening of the sealed case incorporating the first driver fits together with the end portion of the opening of the sealed case incorporating the second driver such that the two sealed cases together with the first and second drivers may rotate relative to each other around their cylindrical axis. The phase difference between the input of the two-partition circuit and the output of the combining circuit changes according to the relative angle of rotation around the cylindrical axis between first and second drivers.

摘要： A booster system for transmitting a received wave after amplifying it comprises a receiving antenna section, a carrier combining section, a transmitting section, a transmitting antenna section and a parameter control section. The carrier combining section multiplies a canceling signal by a cancel parameter to obtain a replica signal, then combines it with a received signal in at least one of the radio frequency band, the intermediate frequency band and the base band, and derives a combined base band signal from the combined signal. The transmitting section generates a send signal and a canceling signal by using a signal demodulated through the demodulation of the combined base band signal. Based on the combined base band signal and the canceling signal, the parameter control section determines a canceling parameter such that the power of the combined base band signal is reduced, the parameter being provided to the carrier combining section.

摘要： The outputs of antenna elements 111 to 11M of a wide directional pattern 12 are distributed by a distributor 13 to respective channel parts 141 to 14N, and in each channel part 14i (i=1, 2, . . . , N), its connection points 311 to 31M to the distributor 14 are divided in groups of P=4; four connecting ends of the respective groups are connected via level-phase regulators 231to 234 to combiners 221 to 22L (L=M/P), then the combined outputs therefrom are applied to receivers 151 to 15L, and the outputs therefrom are combined after being applied to regulators 161 to 16L which are adaptively controlled. In the channel part 141, coefficients W1 to W4 are set in regulators 231 to 234 to obtain a subarray directional pattern 24 and a combined directional pattern 19 is controlled within the range of the subarray directional pattern, and in another channel part coefficients W5 to W8 are set in the regulators 231 to 234 to obtain a subarray directional pattern 26; by setting the regulators 231 to 234 of each channel part, a wide area is covered as a whole.

摘要： Two beams with equiangular spacing are formed at a single antenna face, and multiple beams are generated by combining a plurality of such faces. This makes it possible to reduce the size of an antenna device and to decrease the wind load sustained by an antenna, whereby it becomes possible to mount many antennas on a single supporting structure and to achieve substantial weight reduction of a supporting structure.
