Techniques are disclosed for configuring a broadband antenna system. An example electronic device includes a first antenna operating at a first frequency range and coupled to a first transceiver via a first signal path comprising a first indirect feed. The electronic device also includes a second antenna operating at a second frequency range and coupled to a second transceiver via a second signal path comprising a second indirect feed, wherein the first frequency range is lower than the first frequency range. The electronic device also includes a third antenna operating at the second frequency range and coupled to a third transceiver via a second signal path comprising a third indirect feed. Additionally, the first antenna is coupled to the first antenna and the second antenna by a capacitive coupling element.

Antenna bandwith enhancement for an electronic device

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.

Antenna bandwidth enhancement for an electronic device

Described is an antenna system for wireless communication. The antenna system can include a support plane; a first antenna element coupled to the support plane; and a second antenna element coupled to the support plane and positioned in balance with the first antenna. The support plane can include a slot that is configured to create a balanced relationship between the first and the second antenna elements. The system can include an electrical component connected across a width of the slot and configured to tune a current balance between the first and the second antenna elements.

Antenna system

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.

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.

Frequency reconfigurable antenna decoupling for wireless communication

An antenna arrangement is provided. The antenna arrangement includes a first antenna element and a second antenna element. An inductance coil is coupled to the first antenna element and the second antenna element.

Antenna arrangement

An antenna device, wireless communication device, and method to provide wide banded antenna tuning. The antenna device is configured to include a higher frequency range antenna element, a lower frequency range antenna element, a resonance switch, and high and lower frequency range coupler elements. The antenna device provides a high frequency switch stage and a low frequency switch stage. The high frequency switch stage includes the antenna device being configured to resonate at one or more frequencies within a high impedance bandwidth and the low frequency switch stage includes the antenna device being configured to resonate at one or more frequencies within a low impedance bandwidth. The antenna device further includes impedance tuning circuitry to modify the impedance bandwidths of both the low and high frequency bandwidths. The antenna device is configured to separately perform impedance tuning for each of a transmit signal and a receive signal.

Wide banded antenna tuning

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.

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.

Antenna configuration with a coupler element for wireless communication

A cellular low band antenna is indirectly coupled to communication signals via a first coupler that is located within a same volume of a body as one or more wireless local area network (WLAN) antennas. Various antenna configurations can include the one or more WLAN antennas being indirectly coupled to communication signals via a second coupler within the same volume as the cellular low band antenna. A high band antenna is located in a different volume that is adjacent to the volume of the cellular low band antenna and the one or more WLAN antennas. Another similar antenna system can be provided in a separate volume for diversity communications in a communication device, such as a tablet, laptop or other such communication device.

An antenna module for wireless communication comprises an antenna element, a first port and a second port. The antenna element comprises a first resonance frequency and a second resonance frequency. The first port is configured to receive or provide a first radio frequency signal with a first frequency range and the second port is configured to receive or provide a second radio frequency signal with a second frequency range. The first frequency range is different from the second frequency range. Further, the first resonance frequency is located in the first frequency range and the second resonance frequency is located in the second frequency range. The antenna element is configured to transmit or receive the first radio frequency signal and the second radio frequency signal simultaneously.
