Abstract: We disclose an ultrawide-band (UWB) dual polarization three-dimensional (3D) tapered aperture Vivaldi antenna. It is generally comprised of a radiator having two pairs of tapering arms, each pair corresponding to a different polarization and the tapering arms spaced thereof closest to one another at a feed point location of the antenna and taper outwardly in opposite directions, thus forming a 3D Vivaldi antenna aperture therebetween; and a dual feed balun connecting to each of the two pairs of tapering arms and providing a separate channel for each of the polarizations. Embodiments of our antenna have been designed and simulated using full-wave electromagnetics commercial software. The results for our antennas demonstrate over 20:1 operating bandwidth with good radiation characteristics and very low cross polarization.

Abstract: An antenna device includes a ground plate which is a flat plate-shaped conductor member, an opposing conductive plate which is a flat plate-shaped conductor member installed at a predetermined distance from the ground plate and is electrically connected to a power supply line, and a plurality of short-circuit pins for electrically connecting the opposing conductive plate and the ground plate. One end of a plurality of short-circuit pins extends to a conductive plate plane, which is a plane including the opposing conductive plate, and the other end of the plurality of short-circuit pins extends to the ground plate plane, which is a plane including the ground plate. One or more of the plurality of short-circuit pins connect the opposing conductive plate and the ground plate.

Abstract: A multi-core dielectric circular waveguide (MCDCW) is described. A hybrid mode excitation for multi-core dielectric filled circular waveguide fed parabolic antenna is also described. A multi-core dielectric circular waveguide with four cylinders of different relative permittivity (∈r) inside each other is used to generate the hybrid mode (HE11) directly without need for coupling TE11 and TM11 modes as in prior art corrugated waveguide feeders. This mode is preferable to be used as operating mode to feed the reflector. Four concentric cylinders of different relative permittivity ∈r are used as an example.

Abstract: An antenna module that includes dielectric substrates, radiating elements that are of a plate shape and disposed in or on the dielectric substrates, ground electrodes, and a peripheral electrode. The ground electrode is disposed in or on the dielectric substrate to face the radiating element. The ground electrode is disposed in or on the dielectric substrate to face the radiating element and is electrically connected to the ground electrode. The peripheral electrode is disposed in a layer, in the dielectric substrate, between the ground electrode and the radiating element and is electrically connected to the ground electrode. A direction normal to the radiating element is a first direction from the ground electrode toward the radiating element. A direction normal to the radiating element is a second direction different from the first direction. The peripheral electrode extends from the ground electrode in the first direction.

Abstract: An antenna includes a radiation plate 56 equipped with a radiation surface that radiates radio waves and a feed point that is a location supplied with power from a transmission line. When looking at the radiation plate along a horizontal direction, the feed point is provided at a position separated from a centroid of the radiation plate by a distance A. When looking along a thickness direction of the radiation plate, locations between an end portion of the transmission line connected to the feed point and an intersection portion intersecting with a peripheral edge portion of the conductor plate, overlap in the thickness direction of the radiation plate with a specified area between a third straight line and a fourth straight line.
