in wireless communications, an antenna is an essential device made of conductive metal that transmits or receives electromagnetic radio waves. as the main enabler of wireless communications, antennas must satisfy a number of challenging parameters such as a wide frequency range, flat gain curves and high mechanical stability, so that they can support an ever increasing range of applications.wireless communications testing requires over-the-air (ota) test systems with various antenna types that serve different system functions. a variety of basic antenna designs have become established over time. these include standard gain horn, vivaldi, patch and array antennas. each has unique features that make them ideal for a specific application.test antennas /probes, link/communications antennas and calibration antennas are used in ota test systems.

this document provides the technical specifications of the r&s®ts8991 ota performance test system components.

the r&s®ts8991 ota performance test system performs ota measurements for all important wireless and mobile standards.
