Abstract/Summary
Neutrinos contain information necessary to determine the origins of the universe and cosmic events because they can travel long distances with minimal interaction, preserving information about their cosmic origins. Since neutrinos interact with ice sheets resulting in RF radiation, antennas have been developed to detect RF transmissions.
A compact 'vane structure' (see Fig. 1a) dual-polarized broadband antenna model has been developed, constructed, and characterized according to input reflection coefficient, and co and cross-pol E and H plane radiation patterns using HFSS and Cal Poly San Luis Obispo’s anechoic chamber for the Radio Neutrino Observatory in Greenland (RNO-G) [1]. Its design goal is to detect UHF Askaryan radiation in the 100-1000MHz range from neutrino-dielectric interactions with the Greenland ice sheet.
This senior project has developed a second iteration (see Fig. 1b) of this dual-pol antenna using High Frequency Simulation Software (HFSS) [1] with an acceptable VSWR (< 2) within the 220-1000 MHz frequency band.
To complete this project, this frequency range must cover the entire band for the antenna’s input reflection coefficient, and radiation pattern must have less than 1dB azimuthal variation to meet radiation pattern specifications. A prototype must also be constructed and verified against required performance specifications in an anechoic chamber before deployment in Greenland.
