Features of Electrodynamic Characteristics of Symmetric Slot Lines on a Conducting Infinite Half-Plane in the Microwave Band

Resumo

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.
