摘要：An improved antenna for use with an implantable microdevice, such as amicrostimulator or microsensor, comprises a loop antenna on the case of themicrodevice. The antenna receives data transmitted from an external device, and
transmits data to an external device. Such a loop antenna may be formed from twocylindrical sections separated by an insulating material on the case of the microdevice, orby separating a metal cylinder into two parallel semi-cylinders separated by an insulatingmaterial. A tuning circuit comprising capacitors and/or varactors is used to obtainresonance in the loop antenna, thus creating a sufficiently large effective antennaaperture. In a preferred embodiment, the electrodes of the microdevice are modified toboth perform their primary task of tissue stimulation and to perform a secondary task asthe radiating elements of a loop antenna.
