A-INFO offers one of the most comprehensive antenna portfolios in the RF and microwave industry, spanning frequencies from HF bands up to 500 GHz. This wide range includes precision-engineered antennas for EMI/EMC testing, radar systems, direction finding, telemetry, satellite communications, anechoic chambers, and general RF measurement applications.
Advantages
- Extensive product range covering multiple frequency bands and applications.
- High manufacturing precision ensuring repeatable, accurate measurement results.
- Customisation options for frequency range, gain, polarisation, and mechanical configuration.
Main Antenna Types
- Broadband Horn Antennas: 100 MHz – ~110 GHz, low VSWR, ideal for EMI/EMC testing and gain measurements.
- Standard Gain Horn Antennas: 320 MHz – 500 GHz, typical gains 10–25 dB, linear polarisation.
- Octave & Multi-Octave Horns: Wide bandwidth coverage across multiple octaves.
- Dual-Polarisation Horns: Switchable or simultaneous vertical/horizontal and circular polarisation.
- Conical & Corrugated Horns: Enhanced bandwidth and beam symmetry up to 220 GHz.
- Lens Horn Antennas: Focused beam designs for high-directivity applications.
- Cavity-Backed Spiral Antennas: 0.5–40 GHz, broadband circular polarisation for EMC, direction finding.
- Log-Periodic Antennas: 30 MHz – 18 GHz, linear or circular polarisation.
- Bi-Conical Antennas: 0.1–110 GHz, omnidirectional linear polarisation.
- Microstrip & Omni Antennas: Compact, lightweight designs for portable and embedded systems.
- Parabolic Reflectors: Prime focus and Cassegrain configurations for point-to-point and high-gain links.
Typical Applications
