摘要： There is provided a variable power distributor capable of calculating an error between transmission lines of two systems after building a variable power distributor and correcting the set value of the amplitude/phase according to the error. An error detection method for this and a set value correction method are also disclosed. The variable power distributor includes: a two-way distributor arranged at the input side of a pair of transmission lines consisting of a first and a second transmission line; a 90-degree hybrid circuit arranged at the output side of the pair of transmission lines; and a variable phase device, variable resistance attenuator, and a power amplifier which are arranged at each of the pair of the transmission lines between the two-way distributor and the 90-degree hybrid circuit. The variable power distributor further includes error detection means for monitoring an output signal from the 90-degree hybrid circuit and detecting an error existing in each component between the first and the second transmission line according to the monitor output.

摘要： A combination antenna device wherein a helical antenna which is constituted of a helical element and supplies power to a coaxial line and a monopole antenna which is constituted of an outer conductor of the coaxial line are formed coaxially and therefore a gain in a horizontal plane can be made uniform and an occupation volume can be made small. At an upper end section of a coaxial line (11), a balun (16) connected to an inner conductor (12) of the coaxial line (11) is installed. One end of a helical element (17) constituted of a pair of wire conductors is connected to the balun (16), and the other end is swiveled around the coaxial line symmetrically about the center of the line in the direction opposite to the balun and is connected to an outer conductor (13) at a lower end section of the coaxial line. At the lower end section of the coaxial line, an inner conductor connection terminal (14) connected to the inner conductor of the coaxial line and an outer conductor connection terminal (15) connected to the outer conductor are installed.

摘要： An antenna device, wherein a disk-like reflector (3) reflecting radio radiated from the opening surface (1a) of a circular waveguide (1) is disposed on the circular waveguide (1) at a position facing the opening surface (1a) thereof, and an annular waveguide (4) forming the radiation characteristics of the radio reflected on the disk-like reflector (3) to rotationally symmetric radiation characteristics is formed around the disk-like reflector (3). Even when a large number of grooves (4a) must be formed to provide the rotationally symmetric radiation characteristics, the radial dimension of the disk-like reflector (3) must not be increased. Accordingly, since the presence of an auxiliary reflector does not result in the rise of side lobe level and the deterioration of gain, the gain can be increased, cross polarization can be reduced, and side lobe can be reduced.

摘要： Square waveguides (9a, 10a) and square waveguides (9b, 10b) are symmetrically formed and a waveguide type polarizer (13) is installed below the level of a waveguide type polarizer (8). This provides an effect which enables installation stability to be enhanced with reduced device height without impairing electric characteristics. In addition, the symmetrical arrangement ensures superior weight balance and mechanically stabilized performance.

摘要： A reflector antenna comprising a Cassegrain reflector, and a mechanism for turning the reflector about the azimuth axis and the elevation axis so that it can be installed in a limited space while exhibiting a sufficient practicality and can perform scanning by turning about two axes perpendicular to each other. The reflector of substantially rectangular aperture is subjected to figuring such that the elevation angle thereof passes through the substantially central part of the height dimension of the reflector and the supplied electromagnetic wave is received substantially entirely and reflected and thereby the antenna height does not increase even when the reflector turns about the elevation axis. The reflector may comprises an array of a plurality of reflector elements.
