Electric Probe Measurements on Microstrip |
| |
Abstract: | The aim of the experimental investigation reported here is to measure the electric field of microstrip using a field probe. To establish the accuracy of these measurements, the probe is first calibrated against a known field which is obtained by analyzing a wire suspended axially in a rectangular metal tube. Measurements on a simple wire over ground plane circuit indicate that unshielded structures are basically unsuitable for accurate probe calibration. Finally, the theoretical results predicted by a numerical analysis program for microstrip, published recently, are verified by comparing these with the actual field distribution determined experimentally. |
