LUNASKA simultaneous neutrino searches with multiple telescopes
, 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 ...

Inverted F Type Antenna Design for the Cattle Activity and Estrus Detection Sensor Module
Applied Sciences, 2020 In this paper, an inverted F type antenna (IFA) for ZigBee communication of a sensor board has been designed and optimized, and it replaces the chip antenna on an RF (Radio Frequency) module that is not performing well enough for the ZigBee communication.

Measurements of antenna polar diagrams and efficiencies using a phase-switched interferometer [PDF]
, 1986 It is desirable to know antenna polar patterns and efficiencies accurately. In the past, calibration measurements have been made using balloons and aircraft and more recently satellites. These techniques are usually very expensive. It is shown that under
