Broadband pattern‐reconfigurable water loop antenna, pattern‐reconfigurable water loop antenna

open access: yesIET Microwaves, Antennas & Propagation, 2021
A novel loop antenna is proposed here. This antenna uses an annular arm made of pure water to take the place of the metallic loop of a typical loop antenna. The water arm is enclosed by a resin loop tube.

Suppressing loop current of shielded loops at fundamental resonance [PDF]

open access: yesScientific Reports
In magnetic resonance imaging (MRI), arrays of small loop antennas/coils are extensively used for signal reception. In such arrays, the loop current must be suppressed to prevent transmit antennas or other elements in a receive array from being detuned ...
