Research on Novel Loop Antenna in Microwave Cavity Measurement of Permittivit
Keywords:
avity, couple, loop antenna, resonator.Abstract
Electromagnetic coupling effects on a novel loop
antenna in a TE011 circular cavity are studied theoretically and
experimentally. This novel loop coupling antenna is developed
for avoiding and suppressing the spurious modes in the TE011
circular cavity of the microwave permittivity measurement
system. The operating principles and impedance of the novel
loop antenna are investigated. This method has the advantage of
simple setting and fast tuning of the system. The experimental
results are compliant with simulations.
