An antenna and shield apparatus for detecting phenomenal signals using
nuclear and electronic resonance detection technology, comprising: a
transmit and receive antenna, an electric field shield 60 and an outer
shield 52. The antenna is a multiple parallel loop transmit-receive
antenna forming a main coil assembly 11 having a plurality of loop
segments 20 optionally interconnected by connectors in the form of
conducting bars 10, relays 16, or nothing. The electric field shield 60
comprises an inner sleeve of conducting material 60, 68 disposed on the
inside of the coil assembly 11 for shielding the electric field emanating
from the coil assembly 11 from the target volume circumscribed by the
assembly. The outer shield 52 comprises a central screen portion 55,
waveguides 57 at either end thereof and a sloping channel portion for
interconnecting the two. The coil assembly 11 and the electric field
shield 60 are housed within the outer shield 52.
