In this study, a noninvasive method based on infrared thermography is presented to obtain the resonant frequency of a dipole antenna in the microwave region. The study was performed by visualizing the temperature increase due to the Joule heating of the antenna fed by a voltage source. Results show a significant increase in dissipated heat at 830MHz where the resonance is expected. This method can be used to measure planar antennas noninvasive and in‐situ without having to take them to a specialized antenna‐measurement facility. © 2014 Wiley Periodicals, Inc.
