What are the challenges of measuring mmWave frequencies in 5G?

Measuring mmWave frequencies is challenging due to high atmospheric attenuation and the need for extremely precise antenna alignment. At these frequencies, even minor cable losses or connector imperfections can significantly impact data. Specialized high-gain antennas and low-loss waveguide components are necessary to maintain signal integrity.

How does antenna beamwidth affect 5G base station testing?

In 5G testing, the antenna's beamwidth determines the spatial resolution of the measurement. Narrow-beam antennas pinpoint specific signal beams in Massive MIMO systems, while wider-beam antennas are used for general coverage. Choosing the right beamwidth is essential for characterizing beamforming performance.

What type of antenna is best for 6G research and development?

6G research targets sub-terahertz frequencies, requiring antennas with extreme precision and integrated waveguide interfaces. Horn antennas with specialized small-scale machining are currently the standard for these emerging bands. These antennas must provide stable performance at frequencies often exceeding 100 GHz.

How do I minimize signal loss at frequencies above 26 GHz?

To minimize loss at high frequencies, keep cable lengths as short as possible and use high-frequency rated cables. In many cases, it is more efficient to use waveguide-to-coaxial adapters directly at the antenna port. For the highest precision, using an antenna with a direct waveguide interface eliminates connector-related losses.
