  We have fabricated rhenium microwave resonators from epitaxial films. We have
used thin films of different structural quality depending on their growth
conditions. The resonators were coupled to a microwave transmission line which
allows the measurement of their resonance frequencies and internal quality
factors. From the resonance frequency at low temperature , the effective
penetration depth and the London penetration depth of the rhenium film are
extracted.
