Abstract: The present invention provides an antenna miniaturized topology that is based on the implementation of a conductive loading on a quadrifilar helix antenna. This may be achieved by connecting the tip of the four helical arms to end members which may be circular planar conductors. The miniaturization of the antenna may be further enhanced by incorporating a dielectric material in the space between the four arms.

Abstract: An antenna having a body that includes a plurality of rigid sections separated by a plurality of flexible sections and at least one conductor attached to the rigid and flexible sections. The flexible sections forming hinges that connect rigid sections together to permit the body to be configured into a conical configuration from a substantially flat trapezoid configuration.

Abstract: Provided is an energy harvesting device, including a solar cell including at least one active layer for receiving a first range of electromagnetic frequencies, at least one layer including antenna structures for receiving RF energy and formed on a first side of the solar cell, and at least one semiconductor for absorbing IR energy, and formed on a second side of the solar cell opposite the first side.

Abstract: Embodiments relate to systems and methods for a frequency reconfigurable filtenna system. Implementations incorporate a reconfigurable band-pass filter within the feeding line of an antenna structure. The combination of the filter and the antenna may be referred to as a “filtenna”. Implementations integrate both the band-pass filter and the antenna within the same substrate, permitting easier, more efficient and more compact integration in the transceiver hardware. Moreover, by using this configuration, the biasing of the switching elements are not present in the radiating plane of the antenna. This reduces the negative effect of the biasing lines on the antenna radiation performance, as we!! as provides a tunable filtered antenna radiation characteristic.
