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: Representative implementations of devices and techniques provide self-interference suppression for a transceiver of a wireless communication system. To minimize interference from a transmit signal appearing on a receive path of the system, a cross-correlation is minimized between the transmit signal and a desired receive signal.

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: Antenna systems that can include first and second radiators and an electromagnetic coupler disposed adjacent to the first and the second radiators. The radiators can be tunable to one or more frequencies. The electromagnetic coupler can be, for example, an inductive coupler or a capacitive coupler. One or more of the antenna systems can be configured to use carrier aggregation by tuning the first and/or the second radiators. For example, one or more of the antenna systems can be configured to use inter-band aggregation, intra-band contiguous aggregation, and intra-band non-contiguous aggregation.
