A double ridged horn antenna uses dual rectangular/ridged waveguides to direct RF signals, operating in X/Ku-bands (8–40GHz) with 10–15dBi gain and ≤1.5 VSWR. Constructed from aluminum/copper (silver-plated for low loss), its flared ridges expand wavefronts, enabling efficient emission/reception for high-frequency communication or radar systems, aligned via ±0.1mm precision with feed sources. ​​Basic Definition and Purpose​​ […]

Corrugated horn antennas outperform conventional ones due to their periodic grooved structure (e.g., 0.5–1mm depth, 2–4 grooves/wavelength) that minimizes edge diffraction and surface current scattering, reducing ohmic losses. This design achieves ≥85% radiation efficiency (vs. 60–70% for conventional) with VSWR ≤1.2 across 10–40GHz, optimizing RF energy directionality and reducing wasted power.
