To Design, Simulate, and Analyze TE11 Dominant Mode Circular Wave Guide in X-band

Circular waveguides are noted for being less complicated to construct and install compared to rectangular waveguides. This simplicity contributes to their practicality in various applications. Circular waveguides are frequently used for long-range waveguide transmission, particularly beyond 10 GHz. They are also employed to connect a horn antenna with a reflector in tracking radar systems. Recent advancements in communication systems operating at microwave frequencies have driven the need for the development of technologies like circular waveguides. This progress is crucial to meet the requirements of evolving applications. Our study focuses on characterizing a circular waveguide at a high frequency of 20 GHz. The specified dimensions include length (L) = 1.2874 mm, radius (r) = 14.3 mm, height (h) = 60 mm, and wavelength (λ) = 0.3 mm. E-field, H-field, Voltage Standing Wave Ratio (VSWR), and S-parameters are among the features that have been observed during the characterization study. The simulation is conducted utilizing High Frequency Structure Simulation (HFSS), a widely utilized tool for electromagnetic simulations.
