Bandwidth Enhanced Folded Unipole Antenna for VLF Measurements
Patrick Deibler, Ashanthi Maxworth · 2021
Folded unipole antennas have been used in AM radio communications since mid-90s. These antennas are capable of operating within a large bandwidth. Despite the history, large bandwidth and wide usage rigorous mathematical analysis and simulation results are not widely available for this antenna configuration. In this work, we present mathematical analysis and simulation results for a bandwidth enhanced folded unipole antenna which can be used effectively in the Very Low Frequency (VLF: 3 - 30 kHz) range, while keeping the antenna dimensions feasible.
