Abstract: This document describes a multimode high-isolation antenna system and associated methods and systems. The described antenna system is implemented on a generally-circular printed circuit board and can be used for wideband and ultra-wideband applications. The multimode high-isolation antenna system includes two orthogonal antennas separated by a decoupling structure. This arrangement provides high isolation between the antennas and enables five unique resonant modes of operation for the multimode high-isolation antenna system.

Abstract: Techniques and apparatuses are described that implement a compact multiple-input multiple-output (MIMO) antenna module with two monopole antennas and a decoupling circuit. Due to a physical proximity of the two monopole antennas within the compact MIMO antenna module, the two monopole antennas indirectly couple to each other through one or more coupling paths. The decoupling circuit attenuates the resulting interference by providing a direct coupling path between the two monopole antennas. In this way, the decoupling circuit effectively counteracts the indirect coupling between the two monopole antennas to enable the two monopole antennas to behave substantially independent of each other for MIMO applications. The compact MIMO antenna module can be implemented within space-constrained devices and realize improved performance relative to other antenna modules that have a similar antenna spacing and do not include the decoupling circuit.

Abstract: A dual-mode antenna array receives RF signaling for AoA analysis, and includes a substrate, a ground plane disposed at a first side and a pair of radiating elements disposed at a second side. Each radiating element of the pair includes conductive material arranged in a modified rectangular shape having a first slot at a first side, a second slot at a second side, a third slot at a third side, and a fourth slot at a fourth side. The antenna array further includes a feed probe disposed adjacent to the pair of radiating elements and a pair of feedlines, each feedline conductively connected, at a first end, to the feed probe and connected, at a second end, to each of a first feed point and a second feed point of a corresponding radiating element.

Abstract: This document describes an integrated cellular and ultra-wideband antenna system for a mobile electronic device. The cellular and ultra-wideband antenna are located in close proximity to one another, along with a circuit designed to enhance isolation between the two antennas. The circuit is also designed to enhance the efficiency of the cellular antenna by permitting the ultra-wideband antenna to generate an additional resonance in the cellular band. The integrated cellular antenna and ultra-wideband antenna results in reduced mutual coupling and performance degradation of the antennas, and the cellular antenna may gain enhanced bandwidth and efficiency.

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.
