摘要： A slot antenna apparatus 10 contains a circuit substrate having a high-frequency circuit arranged therein and a shield case accommodating the circuit substrates. A cross-shaped slot and a feeding pin are formed in an upper plate of the shield case. The cross-shaped slot is composed of a first and second slots. The lengths of the slots are different and the slots are perpendicular to each other. The shortest distances from the feeding pin to the first slots are approximately equal. When the power is fed to the upper plate through the feeding pin, the slots are excited to irradiate linearly polarized waves perpendicular to each other, respectively.

摘要： A direction of a power feed patch relative to a rod-shaped antenna is set so that a short axis thereof substantially orthogonally crosses a plane containing an intersection between the short axis and a long axis of the power feed patch of a patch antenna and an axis of the rod-shaped antenna. As a plane of polarization of a linearly polarized electromagnetic wave radiated from the rod-shaped antenna is thereby caused to substantially coincide with a direction of the long axis of the power feed patch and to substantially orthogonally cross a direction of the short axis, even if a powerful wave of a higher frequency than a desired frequency to be received by the patch antenna and difficult to be removed by a band pass filter of a low-noise amplifier circuit is radiated from the rod-shaped antenna, field components of the high frequency electromagnetic wave in the direction of the short axis will become virtually zero.

摘要： A dielectric plate, serving as a 90-degree phase device, is disposed inside a waveguide. A phase-converting portion of uniform thickness is formed at the central portion of the dielectric plate, and stepped portions, serving as impedance converting portions, are formed at both longitudinal end portions of the phase converting portion by causing protrusions to be protrude from both of the longitudinal end portions. The protrusions are disposed on orthogonal axes extending in widthwise and thickness directions of the dielectric plate. The protruding amount of each of the protrusions from end surfaces of the phase converting portion is approximately ¼ of a wavelength &lgr;g inside the waveguide. The end surfaces of the phase converting portion and corresponding end surfaces of the protrusions form reflecting surfaces that are orthogonal to the direction of propagation of an electrical wave.

摘要： In a primary radiator, a dielectric plate is fixed to the interior of a hollow first waveguide having, at one end, an opening shaped like a regular square, and is substantially orthogonal to two parallel sides of the opening. A second waveguide of rectangular cross section is coaxially connected to the other end of the first waveguide. A pair of probes are disposed at an angle of approximately 45° with respect to the dielectric plate so as to protrude from flat inner wall surfaces of the second waveguide toward the center axis.
