Study and design of a loop antenna for application of medical telemetry

In this paper we have studied and designed a rectangular loop antenna powerful around 433.92 MHz and destiny particularly with the medical telemetry where we use band ISM (industrial scientific and medical). We start by seeing the effect of measurements on the performances of this type of antennas then we compare the theoretical results and those of simulation to check our choice. Finally we give a method allowing the improvement of the output.
