We reveal features of the radiation from symmetric constant-width slot lines on a conducting infinite half-plane in the electrodynamic H plane when their widths change and the lengths remain constant. Analysis of the theoretical and experimental results demonstrates that as the slot width increases in the range (0.5–1.5) ⋋0 (the radiation frequency is equal to 10 GHz, the wavelength ⋋0 = 3 cm, and the slot length is 5⋋0), the width of the main lobe of the radiation pattern narrows in the E plane (which is predictable), whereas in the H plane it remains almost unchanged, which is confirmed by the consistent results of the mathematical simulation and experiments.
