摘要： An antenna structure includes four antenna arrays spaced apart from each other. Each of the four antenna arrays has four antennas. A first phase difference between any two adjacent ones of the four antennas is 90 degrees, so that the four antennas can jointly generate a first circular polarization. The four antenna arrays have a common center point, one of the four antennas of each of the four antenna arrays adjacent to the common center point is defined as a shared antenna, and the four shared antennas jointly form a shared antenna array. A second phase difference between any two adjacent ones of the four shared antennas is 90 degrees, so that the four shared antennas can jointly generate a second circular polarization that has a same rotation direction as the first circular polarization.

摘要： Example embodiments relate to a substrate integrated waveguide (SIW) with dual circular polarizations. An example SIW may include a dielectric substrate and a first metallic layer coupled to a top surface of the dielectric substrate with a through-hole extending through the dielectric substrate and the first metallic layer. The SIW also includes a dielectric layer coupled to a top surface of the first metallic layer. A second metallic layer is coupled to a top surface of the dielectric layer. The second metallic layer includes a non-conductive opening, a plurality of feeds with a first end in the non-conductive opening and a second end including a single-ended termination, and an impedance transformer. The SIW also includes a third metallic layer coupled to a bottom of the dielectric substrate, and a set of metallic via-holes proximate the non-conductive opening and coupling the second metallic layer to the third metallic layer.

摘要： This application provides a terminal antenna and a mobile terminal device. The terminal antenna includes a frame, a first feed, and a second feed. A part of the frame on a side of the first gap away from the second gap forms the first conductor, a part of the frame on a side of the second gap away from the first gap forms the second conductor, and the frame between the first gap and the second gap forms the third conductor. The first feed is electrically connected to the first conductor, so that the first conductor radiates a signal, and the second feed is electrically connected to the second conductor, so that the second conductor radiates a signal in a low band.

摘要： A waveguide antenna with an antenna proximal side and an antenna distal side. A number of waveguide openings for transmitting and/or receiving electromagnetic signals to and/or from an environmental space is arranged at the antenna distal side. The waveguide antenna includes an antenna interface structure that includes interface waveguide apertures arranged in an interface carrying surface that extends transverse to a normal axis. Each interface waveguide aperture is coupled with at least one associated waveguide opening such that the respective interface waveguide aperture and the associated waveguide opening(s) are offset with respect to each other transverse to the normal axis. Each interface waveguide aperture and at least one coupled waveguide opening are configured for transmitting and/or receiving electromagnetic signals with respective polarizations rotated against each other. At least two neighboring interface waveguide apertures may be interlaced with each other, and/or the interface waveguide apertures may in each case enable a simultaneous and/or alternative transferring of at least two electromagnetic signals of different polarization, and/or the interface waveguide apertures may have different aperture orientations.

摘要： An antenna module has a substrate, a radiating element disposed in or on the substrate, a power feeding line, and a dielectric body. The substrate has a rectangular shape including first and second sides adjacent to each other. The power feeding line extends in a normal direction of the substrate and transfers radio frequency signals supplied from an RFIC to the radiating element. The dielectric body is disposed on a side surface of the substrate. The power feeding line is coupled to the radiating element at a position offset from the center of the radiating element in a first direction toward the first side. The dielectric body is disposed so as to cover the side surface of the substrate including the first side. The dielectric constant of the dielectric body is higher than the dielectric constant of the substrate.
