We demonstrate detection of high frequency magnetic fields using a cantilever with an integrated magnetic loop. The detection works be frequency mixing with the magnetic fields of a sample. A broadband loop antenna gathers fields to be detected and step-up transforms them at the location of the cantilever. We demonstrate broadband performance of the system by detecting a range of frequencies between 10 and 1000 MHz. The Q of our detection system is extremely high (10,000+), and it increases linearly with frequency. Also, our detection system requires no capacitor, thus minimizing dielectric coupling.
