Enhancing mmWave testing capabilities with Farran's Antenna Extender Transmitters (AET), Antenna Extender Receivers (AER), and Frequency Extension Heads for Vector Network Analysers (VNAs)
APC Technology Group is pleased to highlight Farran Technology’s state-of-the-art Antenna Extender Transmitters (AET), Antenna Extender Receivers (AER), and Frequency Extension Heads for Vector Network Analysers (VNAs). These antenna testing solutions extend the frequency range of standard test equipment, providing high sensitivity and a cost-effective alternative to full system upgrades.
As wireless communication, automotive radar, and millimetre-wave applications continue to advance, the demand for precise and reliable antenna testing has never been greater. Engineers and researchers require accurate tools to measure antenna gain, return loss, and radiation patterns to ensure optimal performance.


The Importance of Accurate Antenna Testing
Antenna characterisation is essential across industries such as telecommunications, automotive radar, security, and spectrum monitoring. Without precise measurements, performance inconsistencies can result in signal degradation, reduced efficiency, and compliance failures.
Key parameters in antenna testing include:
- Gain Measurement: Assesses how efficiently an antenna converts input power into radio waves.
- Return Loss Measurement: Measures the amount of power reflected, ensuring minimal signal loss.
- Radiation Pattern Analysis: Defines the directional distribution of radiated power, which is critical for beamforming applications.
Test & Measurement (VNA Frequency Extension Heads)
Farran’s Frequency Extension Heads integrate seamlessly with VNAs, offering high-accuracy gain and return loss measurements across a wide frequency range. These solutions allow engineers to maximise the capabilities of their existing test setups without the need for a complete system overhaul.
