Low-Footprint Dual-Band Ultra-Wideband Antenna Modules

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.

Dependencies are inferred from the claim text.
