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.
