This is the first article of a two-article series devoted to the return current distribution in a 2-layer FR-4 PCB microstrip line configuration with a solid reference plane.
This article presents the derivation of the far-field criterion for two fundamental wire-type antennas: electric (or Hertzian) dipole and magnetic dipole.
This is the second of the three tutorial articles devoted to the frequency-domain analysis of a lossless transmission line. This article shows numerous methods of calculating the voltage, current, and input impedance at various locations on the transmission line, using the Circuit Model.
