Abstract: 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.
