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).
