The new method of the microstrip antennas diagnosing

Microstrip antennas have been since more than ten years one of the most innovative areas of antenna technology. As the novelty in article, one of possible diagnostic methods of microstrip antennas is presented, which is based on using thermography. Within the method proposed a distribution of temperatures recorded by the thermovision camera on the microstrip antenna surface is used for its diagnostics. The above diagnostics is based on verification of antenna parameters (SWR) influencing local changes of the temperature distribution on the antenna surface. The proposed methodology of antennas diagnostics was discussed basing on the example of three models of microstrip antennas.
