Description

The Mini Wideband Double-Ridged Horn Antenna is a compact, high-performance RF antenna designed for ultra-wideband applications where space, precision, and frequency agility are critical. 🧩 Key Characteristics - Frequency Range: Typically spans 1.5 GHz to 18 GHz, with some designs reaching 0.5 GHz to 18 GHz - Gain: Moderate, around 10–15 dBi, depending on size and flare geometry - VSWR: Low (≤1.5:1), ensuring efficient power transfer across the band - Polarization: Linear (horizontal or vertical), though some models support circular polarization - Impedance: 50 ohms standard 🛠️ Design Innovations - Double-ridged waveguide: The ridges lower the cutoff frequency and suppress higher-order modes, enabling broadband operation - Miniaturization: Achieved through optimized flare angles, ridge profiles, and aperture shaping without sacrificing performance - Materials: Precision-machined aluminum alloy for lightweight durability - Size: Aperture dimensions are often under 30 cm, making them ideal for portable or embedded systems 🚀 Applications - EMC/EMI testing (MIL-STD-461, CISPR standards) - Antenna pattern measurements - Electronic warfare and signal intelligence - Wideband radar and communication systems - Drone detection and tracking (especially in mobile or compact platforms)
