Engineers often turn to VNAs to measure the return-loss characteristics of an antenna, but they must be used carefully ...

To exactly evaluate the two approaches for comparison, we give simple and persuasive examples of electromagnetic coupling systems between a pair of dipole antennas. We first find the far-field kQ ...

The antenna consists of a 275-m long dipole interrupted with a high-voltage switch somewhere along the line. The switch was operated to force charge to remain near the tip rather than reflect and ...
