Anritsu Unveils Cutting-Edge Test Solutions for Next-Gen Networks

Accurate and flexible measurement environments are becoming essential in the research of Reconfigurable Intelligent Surface (RIS) technology, which is gaining attention as a next-generation high-frequency communication solution. RIS technology enables high-frequency signals to penetrate indoor environments, offering great potential in overcoming signal attenuation issues, especially in millimeter-wave (mmWave) communications through building windows.

In a recent demonstration by the Electronics and Telecommunications Research Institute (ETRI) of Korea, Anritsu’s Vector Network Analyzer (VNA) MS46122B was utilized as a key measurement instrument, proving high-precision performance even in compact setups.

ETRI's newly developed technology features a transparent PET film-based micro-antenna array that can be attached to windows to maximize signal penetration without the need for active repeaters.

In the experimental setup shown in the photos, Anritsu's 2-port VNA MS46122B was used to compare S-parameters and transmission loss between glass with RIS film and ordinary glass. The MS46122B is a compact USB-type vector network analyzer supporting up to 43.5 GHz, offering stable and repeatable measurements in both lab and field environments—without the complexity of traditional test setups.

Anritsu VNAs are already widely used in research institutions and industries for evaluating high-frequency materials, antennas, and transmission characteristics. The MS46122B is becoming a core instrument for quantifying the performance of RIS and metasurface technologies.

With scalability for mmWave, FR2, and FR3 bands, the solution is ideal for research teams preparing RIS technology for commercial deployment in the 5G-Advanced and upcoming 6G era.

An Anritsu representative stated, “RIS is a core technology for solving indoor coverage issues in high-frequency communications,” and added, “Anritsu’s MS46122B is a compact, high-performance VNA that ensures reliable measurements even in space-limited environments, contributing to the validation and commercialization of RIS technologies.”
