Summary:A simple circuit model for a broadband electrically small loop transmitter using energy synchronous direct antenna modulation (DAM) is presented. The concept of energy-synchronous DAM using a loop antenna is briefly described and compared to a conventional narrowband transmitter, via time domain simulations of the current on the loop. A brief analysis of the affect of ohmic loss on the stored current is presented. Initial results suggest that the dissipation in the loop is negligible over short symbol durations, but motivates a discussion about the need for a more comprehensive parametric study for this class of DAM transmitters.
