Abstract :
This paper presents a method for optimal design of inductive links using geometric programming. The optimization proposed allows the inclusion of all geometric and electric constraints associated to the link. As an example, we design the dimensions of the primary inductor and frequency when the secondary inductor has a diameter of 4 mm. The set of inductors designed for a distance of 15 mm was implemented. The maximum efficiency measured is 30% at 415 MHz, which agrees with the expected values.
