摘要： In a variable capacitance module capable of achieving necessary variable capacitance ranges, a variable capacitance circuit includes a variable capacitance element and fixed capacitance elements. A first variable capacitance element and a first fixed capacitance element are connected in series, and the series circuit thereof and a second fixed capacitance element are connected in parallel. Accordingly, with reference to the capacitance of the second fixed capacitance element, the range of the combined capacitance of the variable capacitance circuit is provided by a step size of capacitance based on the combined capacitance of the variable capacitance element and the first fixed capacitance element. The first and second fixed capacitance elements are defined by inner-layer flat-plate electrodes in a laminated substrate, and the variable capacitance element is defined by an MEMS element mounted on a top surface of the laminated substrate.

摘要： An array antenna includes a first end portion that has a first plurality of antennas arranged with a spacing d therebetween and a second end portion that has a second plurality of antennas arranged with the spacing d therebetween. In the array antenna, a spacing between respective antennas in both the first and second end portions and are closest to a central portion is set to 2d, which is a value obtained from multiplying 2, which is the number of the antennas constituting each of both end portions, by the spacing d for both end portions. The antennas in the antenna array are continuously selected as a transmitting antenna by switching, and continuously emit transmission signals. The antennas in the antenna array are also successively selected as a receiving antenna by switching. In this way, by switching between transmission and reception of the antennas of the antenna array, nine reception channels CH1 through CH9 that are arranged with a uniform phase difference therebetween are obtained.

摘要： H plane and E plane of a second rectangular waveguide element are inclined at an angle of 45° with respect to H plane and E plane of a first rectangular waveguide element. A connection element disposed between the first and second rectangular waveguide elements has an inner periphery that surrounds a central axis extending in a direction of electromagnetic-wave propagation. The inner periphery includes surfaces parallel to H plane and E plane of the first rectangular propagation path element, and these surfaces form a staircase such that abutting sections between the surfaces parallel to H plane and the surfaces parallel to E plane constitute projections. The staircase is inclined in a direction corresponding to a direction in which H plane of the second rectangular propagation path element is inclined. Accordingly, an electric field is concentrated in the projections of the connection element, and a plane of polarization of an electromagnetic wave propagating through the connection element is rotated from a plane of polarization in the first rectangular waveguide element towards a plane of polarization in the second rectangular waveguide element.

摘要： A conductor member contains a linear feed waveguide extending in a fixed direction and a plurality of horn antennas coupled to the feed waveguide and set at an interval of about one half of a wavelength in the extending direction of the feed waveguide. The horn antennas are formed by horns and coupling waveguides, and the coupling waveguides are set so as to partially enter the feed waveguide. When the size of the spatial coupling portion formed by the entrance is changed, the degree of coupling between the feed waveguide and each of the coupling waveguides changes.

摘要： An antenna apparatus includes two circular waveguides including a fixed-side circular waveguide and a rotation-side circular waveguide, each having a propagation mode in a TM01 mode, and being arranged coaxially with each other while a waveguide-side choke is provided between the two waveguides. A rectangular waveguide is connected to the fixed-side circular waveguide. Thereby, the high-frequency signal fed from the rectangular waveguide to the fixed-side circular waveguide can be radiated from a primary radiator to which the rotation-side circular waveguide is connected. While the circular waveguides and the waveguide-side choke can constitute a rotary joint, by rotating the primary radiator together with the rotation-side circular waveguide, scanning can be carried out with a high-frequency signal radiated from the primary radiator.
