Abstract: An antenna system, comprising: an omni-directional antenna element; and a directional adapter having an electromagnetic reflector. The directional adapter detachably coupled to the omni-directional antenna element. The electromagnetic reflector being offset from the omni-directional antenna element. The directional adapter may be configured to be coupled to the antenna to convert a radiation pattern from an omni-directional antenna radiation pattern to a directional antenna radiation pattern, and configured to be decoupled from the antenna to convert the radiation pattern back into the omni-directional antenna radiation pattern.

Abstract: Feeding a plurality of antenna elements of an array antenna, involves receiving at a photonic substrate at least one transmit modulated optical carrier (TMOC) signal. The TMOC signal is communicated to an array level photonic integrated circuit (ALPIC) disposed on the photonic substrate where one or more optical processing operations are performed involving the TMOC signal to obtain a plurality of element-level optical carrier (ELOC) signals. These ELOC signals are communicated from the ALPIC to a plurality of conversion locations distributed on the photonic substrate. Photodetectors respectively provided at the conversion locations convert each of the ELOC signals to an element-level modulated radio frequency (ELMRF) signal. The ELMRF signal are coupled from each photodetector respectively to one of the plurality of antenna elements.

Abstract: Performance of a photonic integrated circuit (PIC) is improved by using at least one electro-optic (EO) device included in the PIC to perform at least one EO conversion operation whereby an information signal is transitioned from a first signal carrier type to a second signal carrier type different from the first signal carrier type. The first and second signal carrier types are selected from the group consisting of an optical signal carrier and an electrical signal carrier. An operating bandwidth of the PIC is increased by performing electrical signal impedance matching operations directly on the at least one optical media substrate. An improved electrical impedance match is thus obtained between the EO device and a second device exclusive of the PIC.

Abstract: A coplanar waveguide biosensor and methods of use include a coplanar waveguide transmission line and a sample containment structure. The coplanar waveguide transmission line is operable to support the propagation of an electromagnetic signal and includes a signal line and one or more spaced apart ground elements. The signal line is configured to conduct a time-varying voltage, and the one or more ground elements are configured to maintain a time-invariant voltage, a detection region being formed between a portion of the signal line and a portion of at least one of the one or more ground elements. Detection methods are improved through the enhancement of the electric field in the detection region via impedance discontinuities in the signal line and ground elements. The sample containment structure intersects the detection region of the coplanar waveguide transmission line and includes a cavity configured to hold 1 ml or less of sample solution within the detection region.
