Abstract: An antenna assembly includes a conductive plate having a slot formed within the conductive plate. A conductive coupling element is positioned within the slot of the conductive plate to form a slot antenna structure with the conductive plate. At least one conductive radiator element is positioned outside of the slot. An antenna feed structure is electrically coupled to the conductive coupling element and the at least one conductive radiator element. The antenna feed structure is configured to simultaneously resonate the slot antenna structure and the at least one conductive radiator element. The slot antenna structure and the conductive radiator element work in combination to resonate at substantially similar (e.g., overlapping) RF communication bands or at different RF communication bands.

Abstract: An electronic device is described that is configurable to be transitioned from a first operating mode having a first form factor to a second operating mode having a second form factor. The electronic device includes a first device portion and a second device portion that is connected to the first device portion. The first device portion includes an RF antenna. The second device portion includes an antenna adaptation element. The antenna adaptation element is positioned more closely to the RF antenna in the second operating mode than in the first operating mode. The antenna adaptation element is configured to, in the second operating mode, passively counteract or mitigate a shifting of a resonant frequency of the RF antenna that would otherwise occur as a result of the electronic device being transitioned from the first operating mode to the second operating mode.

Abstract: An electronic device disclosed herein includes an antenna that self-tunes frequency responsive to changes to a physical configuration of the electronic device to negate a shift in the resonant frequency attributable to the change in physical configuration.

Abstract: A monopole antenna structure disclosed herein includes a ceramic block with a metallic surface coupled to a feed structure and a planar radiation element electrically floating relative to the ceramic block. The planar radiation element is in a parallel plane alignment with the metallic surface of the ceramic block. When the feed structure provides signal of one or more select frequencies to the metallic surface of the ceramic block, the ceramic block radiates (e.g., transmits a carrier wave) and in turn, excites the planar radiation element to re-radiate the signal.

Abstract: An isolator assembly includes a capacitively-coupled isolator assembly. In some implementations, the capacitively-coupled isolator element may provide multi-band isolation by having an electrically-floating conductive coupling element with a length that is ½ or ¼ of a carrier wavelength. In other implementations, multiple capacitively-coupled elements may be employed to achieve multi-band isolation.

Abstract: There is disclosed a multiband antenna device comprising a conductive elongated antenna element configured for electrical connection to a conductive groundplane at a grounding point, and for electrical connection to a radio transmitter/receiver at a feeding point. The antenna element comprises a first portion and a second portion. The first portion is configured to extend in a first direction along a first outside edge of the groundplane, and then in a second direction along a second outside edge of the groundplane. The second portion of the antenna element is configured to double back next to the first portion in a third, substantially counter-parallel direction back along the second outside edge of the groundplane, and then in a fourth direction along the first outside edge of the groundplane.
