    Abstract: An antenna array that can include a plurality of antenna cells positioned in a global coordinate system of the antenna array. Each of the plurality of antenna cells has a respective local coordinate system and can include a radiating element having a predetermined angle of rotation defined in the global coordinate system and an antenna port coupled to the radiating element, the antenna port being positioned at a particular set of coordinates in the respective local coordinate system. The particular set of coordinates of the antenna port of each of the plurality of antenna cells can be the same.

    Abstract: Techniques are disclosed for providing isolation between a pair of partially overlapping antennas. An example electronic device includes a first antenna coupled to a first transceiver through a first signal path comprising a first feed, and a second antenna coupled to a second transceiver through a second signal path comprising a second feed. The first antenna and second antenna partially overlap. The example electronic device also includes compensation circuitry coupled to the first signal path and the second signal path and configured to generate a compensation signal that provides analog cancellation of an interference signal received at the second antenna from the first antenna.

    Abstract: The disclosure provides a multi-feed antenna including a first conductor layer, a second conductor layer, four supporting conductor structures and four feeding conductor lines. The second conductor layer has a first center position and is spaced apart from the first conductor layer at a first interval. The four electrically connected sections respectively extend from different side edges of the second conductor layer toward the first center position, so that the second conductor layer forms four mutually connected radiating conductor plates. The four feeding conductor lines are all located between the first conductor layer and the second conductor layer. The four feeding conductor lines and the four supporting conductor structures form an interleaved annular arrangement. The four feeding conductor lines excite the second conductor layer to generate at least four resonant modes. The at least four resonant modes cover at least one identical first communication band.

    Abstract: An antenna module includes a main body, an antenna, and a shield electrode. The antenna includes an antenna electrode that covers a side surface of the main body. The shield electrode covers a top surface of the main body without being in contact with the antenna electrode. The main body includes a substrate, a plurality of electronic components and, a first dielectric layer, a second dielectric layer, at least one first ground connection electrode, and at least one second ground connection electrode. The electronic components and are mounted on the substrate. The first dielectric layer covers a first main surface of the substrate. The second dielectric layer covers a second main surface of the substrate. The at least one first ground connection electrode is in the form of a column extending through the first dielectric layer and connects the substrate to the shield electrode.
