Abstract: A wearable electronic device includes a first member and a second member. The second member includes a first, RF-attenuating, portion and a second, electrically conductive portion. A gap exists between the first member and at least the second portion of the second member. One or more transmitter/receivers, such as one or more BLUETOOTH®, BLUETOOTH® low energy, and/or IEEE 802.11 transceivers may be mounted in the first member. The one or more transmitter/receivers are conductively coupled to the second portion of the second member. RF signals generated by the one or more transceivers are emitted from the second portion of the second member.

Abstract: An antenna arrangement includes a switch having an open state and a closed state, a first antenna that operates as a first active driven element in a first frequency band in response to the switch being in the open state, and a second antenna that operates as a second active driven element in a first frequency band in response to the switch being in the open state. The closed state configures the first antenna and the second antenna to operate in a second frequency band different from the first frequency band by operatively coupling a first impedance between the first antenna and a radio frequency ground, and by operatively coupling a second impedance between the second antenna and the radio frequency ground. The first antenna functions as a parasitic element in the second frequency band and the second antenna functions as an active driven element in the second frequency band.

Abstract: Planar (two-dimensional) and volumetric (three-dimensional), metamaterial-inspired, efficient electrically-small antennas. The electric-based and magnetic-based antenna systems are shown to be naturally matched to a source and are linearly scalable to a wide range of frequencies. The systems include a radiating element that is fed by the source through a finite ground plane via a feedline and an electrically-small, one-unit cell made of a metamaterial that is adapted to match the input impedance of the antenna.
