A New Concept for Improving the Performance of Electrically Small Antennas

Using advances in the areas of multi-mode, closely coupled miniaturized radiators and artificially engineered materials, ultra-broadband, highly efficient, electrically small antennas were developed for operation in military communications systems. A low-profile UWB antenna was developed that is composed of two electrically small loops coupled together in their near fields. Each loop has a three-dimensional surface with a bent diamond-arm shape. Half of each loop placed on top of an infinite conducting ground plane is used in the design. Each loop is loaded with a top hat to reduce the lowest frequency of operation of the antenna.

Microwave Radiometer for Advanced Nanosatellite Control Systems

Microwave radiometers measure temperature, water vapor, and cloud ice in the atmosphere, since oxygen and water vapor naturally emit signals in the microwave portion of the electromagnetic spectrum. These signals are measured at different heights and are used to make 3D images of hurricanes, tropical storms, and thunderstorms. The NanoRacks-Microsized Microwave Atmospheric Satellite (NanoRacks-MicroMAS) measures temperature from molecular oxygen. NanoRacks-MicroMAS is a small, low-cost CubeSat containing a miniaturized microwave scanner that paves the way for future constellations of similar satellites, gathering more detailed, more frequent images of severe weather that impacts people on Earth. NanoRacks CubeSats are delivered to the International Space Station (ISS) already integrated within a NanoRacks CubeSat Deployer (NRCSD).

700 MHz - 6 GHz Benchtop Power Amplifiers

AR (Bothell, WA) now provides up to 350 watts of linear output power over the 0.7 to 6 GHz instantaneous frequency band in one benchtop amplifier housing when driven with a signal generator output of 0 dBm. Class A designs can be provided when linearity and ∞:1 output protection is required, or in Class AB configurations when lower cost and higher efficiency are needed with slight sacrifices in linearity and output VSWR protection. Units have a digital display and all amplifier control functions and status indications are available remotely in GPIB/IEEE-488 format, RS-232 hardwire and fiber optic, USB, and Ethernet. These instruments are used for EMC, wireless, or EW applications.
