Abstract: This document describes low-footprint dual-band ultra-wideband (UWB) antenna modules. A described UWB antenna module may be used as an internal part of a mobile device (e.g., cellphone, tablet, and/or other mobile devices). The UWB antenna module includes a multi-layer dual-band antenna that includes a set of multi-layer patch antennas, each patch antenna including a layer with a conductive ground plate, a feeding plate layer, and a parasitic strip layer with two parasitic strips, one configured to resonate at a frequency within a first band of the dual-band antenna, the other configured to resonate at a frequency within a second band of the dual-band antenna. The parasitic strips are electromagnetically coupled to the feeding plate.

Abstract: An electronic device is provided having an antenna that also functions as a display shield for a display of the device. The display shield can separate components for a display module from other electrical components of the electronic device. The display shield can be grounded to an enclosure of the device at least partially by one or more shield grounding clips, and configured to receive and/or transmit radio frequency waves.

Abstract: Techniques and apparatuses are described that implement a metal structure for steering and broadening millimeter-wave (mmWave) antenna coverage. A user device includes at least one mmWave antenna that produces a near-field radiation region and a far-field radiation pattern. Disposed within the near-field radiation region is the metal structure comprising one or more metal pieces. The metal pieces are able to reflect energy associated with the far-field radiation pattern or produce another far-field radiation pattern based on currents induced in the metal pieces by the near-field radiation region in such a way that the far-field radiation pattern from the mmWave antenna is positively affected (e.g., steered and/or broadened). In this way, the far-field radiation pattern can be effectively steered and/or broadened with a simple cost and space-effective design.

Abstract: Techniques and apparatuses are described that implement collocated mm Wave and sub-6 GHz antennas. An apparatus includes at least one mmWave antenna that produces a near-field radiation region and a far-field radiation pattern in a mmWave frequency band. Disposed within the near-field radiation region is a sub-6 GHz antenna that produces a radiation pattern in a sub-6 GHz frequency band. The sub 6 GHz antenna is able to positively affect the far-field radiation pattern from the mm Wave antenna (e.g., via steering and/or broadening). In this way, the mmWave antenna and the sub-6 GHz antenna can be collocated to conserve space while also steering and/or broadening the far-field radiation pattern of the mm Wave antenna.
