The cutoff frequency is the lowest frequency that the transmission line supports electromagnetic wave propagation. The cutoff frequency of the main mode TE₁₀ of a rectangular waveguide (such as WR-90, with a wide side of 22.86mm) is 6.56GHz (formula: f_c=c/(2a)). The cutoff frequency of a coaxial cable is determined by its structure (e.g., about 34GHz […]

Waveguides operate above 1 GHz with lower losses, handling higher power than coaxial cables, which are effective up to 3 GHz. Structure and Mode of Operation Waveguides and two-wire transmission lines, such as coaxial cables, are fundamentally different in how they carry electromagnetic waves. Two-wire transmission lines typically include two conductors, which are often made

The five key parameters of a dipole antenna are resonant frequency, radiation pattern, impedance (typically 73 ohms), gain (about 2.15 dBi), and bandwidth. Resonant Frequency The resonant frequency of a dipole antenna explains a specific frequency at which the antenna operates at the maximum efficiency level. This frequency is resonance as it dictates the antenna’s
