The cut-off frequency is the lowest frequency at which a transmission line supports signal propagation, calculated using 𝑓𝑐=𝑣𝑝2⋅𝑑f c = 2⋅dv p . Determination The cut-off frequency is a critical parameter for efficient system performance without any signal loss for any communication system, such as satellite transmissions and television broadcasting. In fact, the cut-off […]

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
