Economical phased-array antenna for environmental applications [PDF]

open access: yes, 1971
Antenna system handles data acquisition and tracking, functions as a sensitive radio telescope, and serves as a radiometer in earth atmosphere investigations. Antenna's sensitivity permits resolution of solar disk quadrants in Doppler radar observations.

LUNASKA simultaneous neutrino searches with multiple telescopes

open access: yes, 2011
The most sensitive method for detecting neutrinos at the very highest energies is the lunar Cherenkov technique, which employs the Moon as a target volume, using conventional radio telescopes to monitor it for nanosecond-scale pulses of Cherenkov ...

Primary Beam and Dish Surface Characterization at the Allen Telescope Array by Radio Holography

open access: yes, 2011
The Allen Telescope Array (ATA) is a cm-wave interferometer in California, comprising 42 antenna elements with 6-m diameter dishes. We characterize the antenna optical accuracy using two-antenna interferometry and radio holography. The distortion of each

Directional emission of light from a nano-optical Yagi-Uda antenna

open access: yes, 2009
The plasmon resonance of metal nanoparticles can enhance and direct light from optical emitters in much the same way that radio frequency (RF) antennas enhance and direct the emission from electrical circuits.

Coordination and Antenna Domain Formation in Cloud-RAN systems

open access: yes, 2016
We study here the problem of Antenna Domain Formation (ADF) in cloud RAN systems, whereby multiple remote radio-heads (RRHs) are each to be assigned to a set of antenna domains (ADs), such that the total interference between the ADs is minimized.

The Silver Lining: A Novel, Inkjet-Printed Mesh Coplanar-Slot Antenna for the UHF Band [PDF]

open access: yes, 2018
The Federal Communications Commission (FCC) is opening up frequencies within the television range (400MHz to 700MHz) of the Ultra High Frequency (UHF) band for use in emerging technologies, such as cognitive radio networks and machine-to-machine ...
