Earth station antenna sizes vary by frequency: Ku-band (12-18GHz) systems often use 1.2–4m dishes, while C-band (4-8GHz) requires larger 3–12m apertures to maintain gain for long-distance satellite signal transmission. Basic Antenna Types For instance, a C-band (4-8 GHz) satellite link might use a 2.4-meter antenna for a decent quality signal, while a high-throughput Ka-band (26.5-40 […]

UHF antennas often require a ground plane, typically sized at ½-wavelength (15–50cm for 300–3000MHz), to stabilize radiation patterns, reduce interference, and improve efficiency by 15–20% compared to designs without one. What is a ground plane For frequencies in the UHF band (300 MHz to 3 GHz), the ideal ground plane is often a circular metal
