Dual-band microstrip patch antenna based on short-circuited ring and spiral resonators for implantable medical devices

Along this document, an innovative dual band microstrip patch antenna is proposed for implantable medical devices. Particularly, the covered bands are MICS (402-405 MHz) and ISM (2.4-2.48 GHz). The antenna has a multilayer configuration where the feeding line and the radiating elements are located at different levels. The radiating elements of the antenna are a split ring resonator (SRR) coupled to a Spiral. Both elements are short-circuited to the ground plane to achieve size reduction. In addition, the effects of human body geometry and dielectric properties on the characteristics of the proposed design are studied. Three models of the human body are investigated: one-layer, three-layer and a realistic human body based on the Voxel Man dataset. Finally, simulated results have been validated by measuring return losses of the antenna embedded in mimicking gels, radiation patterns (in anechoic chamber) and radiation efficiency (in reverberation chamber).
