Abstract: Methods, systems, and devices for wireless communications are described. An antenna structure for wideband coverage may include a first bowtie antenna disposed in a first plane. The first bowtie antenna may be, for example, an elliptical bowtie antenna or a triangular bowtie antenna. The antenna structure may also include a plurality of additional bowtie antennas, each of the plurality of additional bowtie antennas disposed in a different plane parallel to the first plane. The first bowtie antenna and the plurality of additional bowtie antennas may be stacked in a first direction perpendicular to the first plane to form a bowtie antenna stack. The antenna structure may include a plurality of bowtie antenna stacks. The antenna structure may also include a staggered conductive wall.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may use transmissions causing power density exposure (PDE) to nearby users. To reduce the PDE of an antenna module (e.g., below a maximum PDE threshold), the UE may implement a shielding strip around the antenna module. For example, the antenna module may include a substrate having a first surface and a set of antenna elements on the first surface. The shielding strip may enclose the set of antenna elements of the antenna module and extend away from the first surface above the antenna elements. The shielding strip may reduce PDE outside a field of view of the antenna module. Additionally, in some cases, the placement of the antenna module in the UE and the materials used for constructing the UE may further reduce PDE.

Abstract: An antenna structure is disclosed that includes a first antenna extending from a substrate, a second antenna formed on the substrate, and first and second parasitic elements formed on the substrate. The first antenna provides an omni-directional radiation pattern in the azimuth plane for vertically polarized signals, and the second antenna provides an omni-directional radiation pattern in the azimuth plane for horizontally polarized signals. The parasitic elements absorb and re-radiate electromagnetic waves radiated from the second antenna.

Abstract: Methods and systems for operating a base station to reduce beam squinting include determining a lower bound on the number of directional beams used by the base station for millimeter wave wideband communications (e.g., based on operating conditions of the base station or wireless devices within the coverage area of the base station) and transmitting synchronization signal block (SSB) messages in an SSB Burst Set consistent with the determined lower bound on the number of directional beams used by the base station for millimeter wave wideband communications.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit control signaling indicating a set of beamforming configurations associated with a set of antenna panels at the UE. The UE may select one or more antenna elements of at least one antenna panel of the set of antenna panels based on a beamforming configuration associated with the at least one antenna panel. The UE may generate a set of beam weights for a wireless communication based on the beamforming configuration and the one or more antenna elements, and may use the generated set of beam weights to transmit the wireless communication. In some examples, the UE may include, in the control signaling, indications of a set of beamforming properties, a number of beam weights, a resource differential, or a combination thereof, associated with each beamforming configuration.

Abstract: An antenna assembly includes an array of patch antennas arranged above a rectangular ground plane. The patch antennas are arranged in a sequence beginning at a first end of the rectangular ground plane and continuing across a width of the rectangular ground plane to a second end. With regard to this sequence, a plurality of polarization feeds alternate between being adjacent a first corner to being adjacent a second corner of the patch antennas and/or a plurality of via walls alternate in orientation along portions of a first edge of the rectangular ground plane and along portions of a second edge of the rectangular ground plane.

Abstract: Aspects of the present disclosure relate to utilizing an intelligent reflecting surface (IRS), a tracking algorithm, or both, to receive, calibrate, and maintain orbital angular momentum (OAM) signaling between wireless devices. The present disclosure describes a first wireless device transmitting spatial-multiple input-multiple output (MIMO) beams to the IRS such that reflected waves from the IRS form a spatial mixture of OAM modes. The IRS may reflect such OAM modes to a second wireless device for subsequent reflection (e.g., a second IRS), reception, calibration, and optimization. For example, the second wireless device may perform pattern recognition of the concentric OAM modes (e.g., by estimating ellipse geometry) to determine the modes of the OAM signaling. The second wireless device may also perform decorrelation, where small perturbations to the elliptical OAM geometry allow the second wireless device to perform one or more optimization techniques related to the OAM signaling.
