Dear Forum,

Does anyone know how to simulate an magnetic loop antenna, and obtain its current density?

Antenna Parameters (see picture)

3 x 3 inches loops

FR-4 Substrate

Frequency of interest 13.56MHz

I want to know how much current/meter there is at a distance of 40mm from the surface. Does anyone know how to setup this problem and measure its current density? if anyone has done this before, can you tell me how to do it?

Regards,

rjrodrig

Momentum solves for currents on the conductors, and you can plot *current densities on the conductors*. What you are looking for is a visualization of the *magnetic field*. This is not available in the Momentum current density viewer, because the E and H fields are not solved explicitely.
