What is the feeding structure of an antenna
The feeding structure of an antenna delivers RF energy from the transmitter to the radiating elements. Common types include coaxial feeds (50-75Ω impedance), microstrip lines (for patch antennas), and waveguide feeds (for high-power applications). Key parameters are impedance matching (VSWR <2:1), bandwidth (e.g., 2:1 for log-periodic antennas), and insertion loss (<0.5dB). Proper design ensures efficient […]
