Antenna overview for Rohde & Schwarz OTA test systems - Flyer
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.
