We report the development and test of planar microwave Inverse Anapole Resonators (IARs) made of superconducting Yttrium Barium Copper Oxide (YBCO) for electron spin resonance spectroscopy on small samples. We first characterize our resonators in zero field and then by carrying out transmission spectroscopy on a diluted \(\alpha ,\gamma \)-bisdiphenylene-\(\beta \)-phenylally (BDPA) organic radical spin ensemble in an applied magnetic field. These IARs allow us to carry out electron spin resonance spectroscopy both in continuous-wave and pulsed-wave mode, and to estimate the spin memory time of BDPA. The comparison with the results obtained for the same sample on typical linear coplanar resonators shows an improvement by \(\approx 2\text { - up to}\,3\) – orders of magnitude in spin sensitivity, with effective sensing volumes below 1 nanoliter. The best sensitivity we achieved is \(S\approx \,10^{7}\,\text {spin}/\sqrt{\mathrm{Hz}}\) in the pulsed-wave regime. These results compare well with similar experiments reported in the literature.
