An audio transmission antenna array may be used to create multiple wireless audio beams, such as using beamforming and beam-steering. For example, individual control of the amplitude and phase of the radio frequency signals fed to each of the antenna elements within the array may be used to create a desired combined antenna pattern. This subject matter may be used for an audio streamer accessory, which may be used to stream audio wirelessly from a source directly to a hearing device, such as streaming audio from a TV to a viewer's audio streaming device. This may be used to provide improve audio performance in environments where multiple users stream audio from a single audio device, or where one or more users are moving around while using the streaming audio device. This may also be used to reduce or eliminate choppiness of audio that a digital audio source can produce.

The present disclosure relates to spherical dual-polarization phased array weather radar. The spherical dual-polarization phased array weather radar comprises a spherical crown phased array antenna module, a digital transceiver module and a signal processing module, wherein the spherical crown phased array antenna module comprises a spherical support frame and a plurality of dual-polarization micro-strip radiation units; the dual-polarized micro-strip radiation units are tightly arranged on the spherical support frame; the spherical crown phased array antenna module is used for detecting weather; wireless transmission is carried out between the digital transceiver module and the spherical crown phased array antenna module; the digital transceiver module is used for generating a frequency modulation signal or a phase coding signal required for detecting meteorological targets and receiving an echo signal reflected by the target; and the signal processing module is connected with the digital transceiver module.

An antenna module includes a radiating element and a dielectric substrate. The dielectric substrate includes a flat portion on which an external terminal (T) to which a RFIC is connected is disposed, a flat portion in which the radiating element is disposed, a bent portion, a feeder, and a ground electrode (GND1). The feeder extends through the flat portions and the bent portion to connect the external terminal (T) and the radiating element to each other. The ground electrode (GND1) extends through the flat portions and the bent portion along the feeder. At the bent portion, a thickness of the feeder is greater than a thickness of the ground electrode (GND1).

An antenna device includes a plate-shaped radiating element that radiates a radio wave polarized in an X-axis direction, a grounding electrode (GND), and a dielectric substrate that carries the radiating element and the grounding electrode (GND). In the dielectric substrate, dielectric in designated regions, which are included in adjustment regions that are located on the outer side with respect to first boundary planes and on the outer side with respect to second boundary planes, is thinner than dielectric in a non-adjustment region. The first boundary planes are planes extending on end faces of the radiating element on the respective sides in an X-axis direction (polarization direction) and being orthogonal to the X-axis direction. The second boundary planes are planes extending on end faces of the radiating element on the respective sides in a Y-axis direction and being orthogonal to the first boundary planes and to the Y-axis direction.

A multibeam antenna including a substrate, and further includes an antenna element, a first guiding apparatus, and a second guiding apparatus disposed on the substrate. The antenna element includes a first pole configured to receive a feeding signal and a second pole that is grounded. The first guiding apparatus enables a first beam generated by the antenna element to radiate in a first direction, and the second guiding apparatus enables a second beam generated by the antenna element to radiate in a second direction. A phase center of the antenna element is at an intersecting point of a first axis and a second axis, the first axis passing through a phase center of the first guiding apparatus and parallel to the first direction, and the second axis passing through a phase center of the second guiding apparatus and parallel to the second direction.
