Corrugated Horn Antenna 22dBi Typ Gain, 140-220GHz Frequency Range RM-CGHA5-22

Corrugated Horn Antenna is a high-performance microwave antenna designed with periodic grooves or corrugations along its inner wall. These corrugations effectively suppress surface currents, resulting in exceptional beam symmetry, ultra-low sidelobes (< -30 dB), and reduced cross-polarization (< -40 dB). Its smooth radiation pattern and stable phase center make it particularly suitable for applications requiring precise wavefront control, such as satellite communication feed systems, radio astronomy (e.g., telescope receivers), and metrology systems. The antenna supports wide bandwidths (e.g., 1.5:1 frequency ratio) with minimal return loss (VSWR < 1.2), ensuring reliable performance in high-precision environments.
