APPLICATION NOTE 3621
Small Loop Antennas: Part 1―Simulations and Applied Theory

Abstract: Small-aperture UHF antennas for remote-keyless-entry (RKE) applications can be terminated either as a
shorted or open loop within a fob. Depending on how the loop is terminated, its far-field pattern and the antenna's
characteristic impedance will be influenced.

In this application note we will explore antenna theory and design using EZNEC, an easy-to-use antenna simulator.
We will measure the antenna's characteristic impedance through our application board. The results will show the
tradeoffs between open and shorted loops, the effects of the ground……
