S/C-Band Luneberg Lens Array Antenna

The S/C-band Luneberg lens array antenna uses circular-aperture dual-ridge horn antennas with integrated Luneberg lenses as radiating elements, arranged in a 4×6 configuration. The entire system adopts a compact design, highly integrating 24 antenna elements, featuring high gain and structural compactness.

Main Functions:

1. Wideband High-Power Radiation: Operates across the 2–6 GHz S/C wideband; each channel withstands input power of no less than 200 W, enabling efficient transmission and reception of electromagnetic wave signals—suitable for high-power applications.

2. High Gain and Beam Focusing: Through the Luneberg lens-loaded array design, achieves high gain (up to ≥26 dBi) across the entire frequency band, effectively focusing energy into a narrow beam to enhance detection capability for distant or weak signals.

3. Wide-Angle Beam Coverage: Leveraging the array layout and lens characteristics, provides inherently wide beamwidth in both azimuth and elevation planes, enabling effective coverage of broad airspace without requiring complex beam-scanning mechanisms. 4. Compact Integrated Design: Integrates 24 antenna elements within a tightly constrained envelope, limiting total weight to under 50 kg—achieving an optimal balance between high performance and structural compactness for easy installation and deployment.
