Considerations on the use of Three-Loop Antenna Systems for Biomedical Applications

Three-loop antenna systems (TLASs) have the ability to simultaneously detect all of the components of the electromagnetic field. Since being invented, TLASs have been deployed in a limited scope of applications, with electromagnetic compatibility testing being the primary use. We show that TLASs have a frequency independent response to centrally located electric dipole moment sources and propose that TLASs offer unique advantages compared to micro-probes when sensing electrically small sources. We suggest two specific applications where TLASs could be used: sensing electromagnetic emissions from microorganisms and electroencephalography screening.
