Advancing 5G Calibration Methods In The Compact Antenna Test Range - A single antenna approach for over the air testing from 18 GHz to 110 GHz

Abstract

This project presents a study on the calibration methodologies for OTA testing in CATR chamber, focusing on the frequency span of 18 GHz to 110 GHz. We introduce a single-antenna method, proving it more efficient and accurate than traditional multi-antenna setups. The research also delves into the challenges of highfrequency signal testing in 5G and upcoming 6G communications. These challenges include signal propagation issues and the complexity of signal processing techniques. Through a two-phase approach, our research validates the new calibration method and assesses the signal generation and measurement system’s performance.
