Ever since the deployment of the first-generation of mobile telecommunications, wireless
communication technology has evolved at a dramatically fast pace over the past four …

Recent wireless communication systems, including the 5G communication New Radio (NR)
operating in the millimeter-wave (mm-wave) bands, demand performance measurements …

Over-the-air (OTA) performance evaluation requires large investments in anechoic
environments. The question of minimizing the test distance is hence critical, and even more …

Near-field measurements, which are performed in-situ, may suffer from the fact that the
antenna under test (AUT) cannot be accessed to transmit or receive a specifically tailored …

In the line of work to devise a compact antenna for 3.5 GHz 5G services, a split‐ring
resonator comes into play. This metamaterial structure takes a smaller area than the open …

As 5G mobile services keep pursuing higher speeds of data transmission based on the use
of mm-Waves, they run across problems. The strength of the mm-Wave signal becomes …

For E-band wireless communications, a high gain steerable antenna with sub-arrays is
desired to reduce the implementation complexity. This paper presents an E-band …

Near-field antenna measurements together with corresponding near-field to far-field
transformations are commonly performed with time-harmonic fields. In in-situ measurement …
