06.24.14 -- Harnessing Magnetic Vortices To Make Nanoscale Antennas
Picking The Pattern For A Stealth Antenna By Francesca De Vita, Simone Di Marco, Fabio Costa, and Paolo Turchi — Altran Group, Italy
A frequency selective surface that acts as an RF filter and helps reduce the radar cross section of antennas consists of a pattern of geometrical objects. There are literally thousands of possibilities, and testing each one physically would take enormous amounts of time. With simulation, though, we can find promising candidates in just minutes.
The 2014 APS-USNC-URSI Symposium is an international forum for the exchange of information on state-of-the-art research in antennas, electromagnetic wave propagation, radio science, and electromagnetic engineering. This symposium and meeting are co-sponsored by the IEEE Antennas and Propagation Society (AP-S) and the U.S. Committee of the International Union of Radio Science (USNC-URSI). The symposium generally attracts over 1,500 attendees from around the world.
Delcross Savant Tilt-Rotor Aircraft Video Delcross Savant provides EM analysis of antennas installed on electrically large platforms. This presentation shows the analysis of a microwave antenna located above the crew compartment of a tilt-rotor aircraft. The 3D radiation pattern is animated as the props turn and the engine orientation rotates.

L-Band planar array antennas from API Technologies feature high gain (typical 14 dB), wide bandwidth, linear polarization, and low return loss. Custom solutions are available that can include customer-defined frequencies, pattern and polarization, non-standard frequency ranges, form factor, and other options.
Because antennas are so close together in modern cell phone stations, they can’t help but affect each other. This application note discusses a case in which a continuous impairment in the GSM 900 band was affecting a station’s performance, and how Narda’s IDA 2 interference and direction analyzer was able to help.
The L1/L2PNRRKIT is a re-radiating system which allows you to re-radiate the GPS L1/L2 carrier indoors. The L1/L2PNRRKIT consists of a plug-in re-radiating amplifier with a wall-mount plug-in transformer that powers the entire system, as well as a re-radiating antenna.
With the Scope/IQ option, the NRA and IDA instruments allow you to generate IQ data from the received data and display, demodulate, store them, and transmit them block by block or as a continuous stream via a remote interface. What, though, is the significance of this IQ data? What are they used for? And, how are they obtained using NRA and IDA?
