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.
Index Terms—Cavity, couple, loop antenna, resonator.
