The Ku-band Polarization Identifier
The Ku-band Polarization Identifier (KUPID) will integrate a very low noise 12-18 GHz, correlation polarimeter onto the Crawford Hill seven meter, millimeter-wave antenna. The primary components of the polarimeter will be built at the University of Miami and other key components, including the microwave horn and data acquisition system will be built at the University of Chicago and Princeton Un...
متن کاملA Novel Digitally Polarization Tracking Antenna for Ku-band Mobile Satellite Communication Systems
This paper presents a novel electrical polarization tracking method for mobile satellite communication systems that use linear polarization. It consists of two main technologies; the first estimates the mobile station antenna’s relative polarization angle against that of the satellite’s onboard antenna, the second forms counter polarization against the estimated value. We use a Ku-band communic...
متن کاملDesign Of 11 GHz Ku-Band Amplifier
Abstarct Amplification is one of the most basic and prevalent RF/Microwave circuit functions. This paper describes the design of an 11 GHz PHEMT ATF-36077 microwave amplifier. The amplifier is manually designed using conventional technique, Smith chart was used to do a matching of the input and output of the amplifier. A completed design of the amplifier was optimised using Hewlett-Packard Adva...
متن کاملMicrostrip Antenna for X and Ku Band
A design of microstrip patch antenna gap coupled with two parasitic elements on its non-radiating edges and a single parasitic element on its radiating edge for the operation in X band and Ku band is proposed here. The parasitic elements are partially shorted. This design is giving an impedance bandwidth of 4.967GHz. This antenna is operating over a frequency range of 11.2334 to 16.0431 GHz wit...
متن کاملGlobal Snow Signature in Ku-Band Backscatter
We present Ku-band backscatter signatures of snow for applications to global snow monitoring with NASA Scatterometer (NSCAT) on the ADEOS satellite and the SeaWinds scatterometer on the QuikSCAT satellite. We carried out the 1999 Alaska Snow Experiment to study the relation between Ku-band backscatter and snow physical properties. The experimental results are applied to interpret backscatter da...
