Ultra-Wideband Double-Ridged Horn Antenna

The ultra-wideband double-ridged horn (UWB-DRGH) is a directional radiation antenna developed on the basis of conventional double-ridged horns.

The ultra-wideband double-ridged horn (UWB-DRGH) is a directional radiation antenna developed on the basis of conventional double-ridged horns. By adopting optimized ridge tapering design, improved feeding structure and innovative mechanical configuration, it achieves an ultra-high bandwidth ratio of 10:1~100:1. It covers mainstream frequency bands from 0.5–40 GHz and advanced versions up to 0.5–50 GHz, acting as a core antenna for EMC / anechoic chamber testing, ultra-wideband radar and broadband communication systems.

Structural Advantages

Double-Ridged Configuration

Loading ridge conductors on the inner waveguide wall lowers the cutoff frequency of the dominant mode and raises the excitation frequency of higher-order modes, greatly extending the single-mode operating bandwidth.
Tapered Transition Structure

Exponential or Bessel curve tapers are adopted between the waveguide section and horn section to realize continuous impedance optimization and smooth transition.
Compact Size

The ridged design reduces the overall volume by 30%~50% compared with traditional horn antennas, facilitating system integration and installation.

Core Characteristics of UWB Double-Ridged Horn Antenna

Ultra-wide frequency coverage;
Stable high gain performance across the full broadband range;
Low sidelobe level for high-efficiency signal radiation and transmission.
