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: Cellular antennas having a mutual coupling can be isolated by the generation of an additional current path along a ground plane. A first antenna element can resonate at a resonance that interferes with and is mutually coupled to a second antenna element operating in a same frequency range, such as a low band frequency range. One or more parasitic scattering elements can generate the additional current path between the two antennas and isolate the two antennas from one another. A parasitic scattering element can comprise two capacitors that alter a radiation pattern of one of the antennas and decrease a correlation between both antennas.

Abstract: An antenna having a passive antenna element that is integrated in a wireless communication chassis, is naturally in resonance, and is galvanically coupled to ground, and a passive indirect antenna element feed that is non-galvanically coupled to the antenna element. If the chassis is foldable, a parasitic element may be located opposite an antenna element feed when the foldable chassis is in at least one of a closed mode and a tablet mode.

Abstract: Described are an antenna system for wireless communication and a method of configuration thereof. The antenna system can include a first radiator having a first resonance frequency, a second radiator having a second resonance frequency different from the first resonance frequency, a first electromagnetic coupler associated with the first radiator and a first frontend, a second electromagnetic coupler associated with the second radiator and a second frontend, and a switch. The switch can be configured to connect the first electromagnetic coupler and the second electromagnetic coupler in an inter antenna aggregation configuration in a first mode of operation. The switch can also be configured to connect the first electromagnetic coupler and the second electromagnetic coupler in an intra antenna aggregation configuration in a second mode of operation.

Abstract: An apparatus and method to provide isolation between a first antenna and a second antenna, each of which is located on a ground plane. A slot that is tunable by a variable reactance is located on the ground plane, the slot not being appreciably resonant at the operating frequency of the first antenna and the second antenna. The antennas operate in an orthogonal mode. Varying the slot reactance varies the electrical distance over which the coupling current between the two antennas flows. Increased RF isolation to a desired magnitude results by maintaining the orthogonality at desired bands. The RF isolation can be measured and a departure from the desired magnitude of isolation causes the reactance to be varied to increase the RF isolation back to the desired magnitude. The antennas and the slot are placed at locations on the ground plane of high current density.
Abstract translation: 一种在第一天线和第二天线之间提供隔离的装置和方法，每个天线都位于地平面上。 通过可变电抗可调谐的槽位于接地平面上，槽不会在第一天线和第二天线的工作频率处明显地共振。 天线以正交模式工作。 改变时隙电抗会改变两个天线之间的耦合电流流过的电距离。 通过将正交性保持在期望的频带，将RF隔离增加到期望的幅度。 可以测量RF隔离，并且与期望的隔离幅度的偏离导致电抗变化以将RF隔离增加到期望的幅度。 天线和槽被放置在高电流密度的接地平面上的位置。

Abstract: A first antenna element is indirectly coupled to communication signals via a coupler that is located within a same volume of a body. A second antenna element is proximate to and adjacent the first antenna element. The first antenna element is configured to operate in a first frequency range and the second antenna element is configured to operate within a subset of the first frequency range concurrent with or simultaneously to the first antenna element. The coupler can operate to couple multiple antenna elements operating at different frequencies within the same volume of the body.
