    摘要: In one embodiment, a dynamically reconfigurable bandpass filter includes a resonator loop and a microfluidic channel proximate to the resonator loop, the channel containing a conductor, wherein the position of the conductor within the channel can be adjusted to change capacitive loading of the resonator loop and therefore change the frequencies that the filter passes. In another embodiment, a filter includes a second resonator loop having comprising switches located at discrete positions along a length of the second resonator loop, wherein opening and closing of the switches changes the effective length of the second resonator loop to change capacitive loading of the first resonator loop.

    摘要: Various examples are provided related to hybrid multiple-input/multiple-output (MIMO) architectures. Beam steering can be provided using lens arrays. In one example, a hybrid antenna system includes a plurality of lens antenna subarrays (LAS), each of the LAS including a plurality of antenna elements configured to selectively receive a radio frequency (RF) transmission signal from RF processing circuitry, and a lens extending across the plurality of antenna elements. The RF transmission signal can be provided to a selected antenna of the plurality of antenna elements via a switching network and a common phase shifter for transmission. The lens can be configured to steer a RF transmission generated by the selected antenna in a defined direction. The selected antenna can be determined by the switching network configuration.

    摘要: An array of backward diodes of a cathode layer adjacent to a first side of a non-uniform doping profile and an Antimonide-based tunnel barrier layer adjacent to a second side of the spacer layer have a monolithically integrated antenna bonded to each backward diode. The Antimonide-based tunnel barrier may be doped with, for example, a non-uniform delta doping profile. An imaging/detection device includes a 2D focal plane array of an array of backward diodes, wherein each backward diode is monolithically bonded to an antenna, which array is located at the back of an extended hemispherical lens, and wherein certain of the arrays are tilted for correcting optics aberrations. The antennas may be a bow-tie antenna, a planar log-periodic antenna, a double-slot with microstrip feed antenna, a spiral antenna, a helical antenna, a ring antenna, a dielectric rod antenna, or a double slot antenna with co-planar waveguide feed antenna.
