Abstract

Antennas are an inherent part of any wireless communication system and efficient use of energy and utilization of the spectrum are requirements for the next generation of high-speed and high-quality communication systems. A raft of emerging wireless technologies such as multiple-input-multiple-output (MIMO), Orbital Angular Momentum (OAM), etc. is increasingly emerging in the arena of modern devices and system design [1]. Furthermore, technology advancements together with spectrum scarcity has driven the exploration of new radio frequency (RF) spectrum suitable for emerging wireless technologies in the millimetre wave (mm-wave), terahertz (THz) and even optical frequency bands. All types of omni-directional and directional antenna measurements have their associated uncertainties, which are unavoidable due to limitations of the measurement instrument capabilities. Their measurement results can only be relied upon with confidence when all the uncertainties associated with an antenna measurement result are fully understood and known. Therefore, it is important to evaluate their measurement uncertainty to quantify the reliability of the measurement result. The traditional 18-term errors that have a direct impact on the accuracy of the far-field beam pointing of an antenna measured in the near-field has been given in [2]. This uncertainty analysis can be extended to far-field and compact range measurements. Furthermore, the Institute of Electrical and Electronics Engineers (IEEE) Standard 149 [3] has recently been revised providing the most up to date IEEE Recommended Practice for Antenna Measurements whereby the source of uncertainty in antenna measurements are discussed in detail in its Chapter 13 including showing an example table for compact range uncertainty analysis. In this paper, we discuss the current measurement challenges and future developments required for improving antenna measurement uncertainty.
