349. Nearfield Validation of a Flexible Solid Phantom for mmW Antennas

Rossella Rizzo

This paper investigates the applications of a solid silicone-carbon-based phantom for nearfield antenna characterization at millimeter-wave (mmW) frequencies. Unlike conventional phantoms designed to mimic permittivity, this phantom is optimized to replicate the skin’s reflectivity. Numerical simulations are performed to compare the phantom’s response to a homogeneous skin model, focusing on...

In this study, we developed a non-reflecting absorbing structure (film) for fast OTA and reference levels measurements above 6 GHz. Infrared (IR) imaging is used enabling non-perturbing, fast, and broadband 2D measurement with sub-mm resolution, in the far as well as in the near field. The absorbing film is designed to minimize perturbance of the antenna under test, which enables measurements...

352. Reflection Properties of the Human Skin From 14 to 42 GHz

With the rollout of 5G in frequency range 2 (FR2) mm-wave in the 26.5 to 30 GHz range in various countries as well as a raft of EU projects addressing health risks of 5G FR2 there is a requirement to enhance the knowledge base on skin reflection properties. In 2021 an extensive study was published by Christ et al, however, the lowest measurement frequency was 40 GHz, this is above the highest...

353. Auto-Induced Downlink Radiofrequency Electromagnetic Field Exposure at 26 GHz using a Multi-Layered Skin Model

The 5th generation cellular mobile networks uses precoding techniques to focus electromagnetic fields (EMFs) emitted by base stations at the user equipment (UE). In this work, this type of exposure, denoted as auto-induced downlink exposure, is studied. The exposure scenario consists of a UE positioned next to the skin. The working frequency is 26 GHz and the UE can have a parallel or...

354. Calibration and Validation Methods for a sub-THz Near-Field Test System

This paper presents calibration and validation methods for a novel electric (E-) field-sensing approach in the near field of sub-THz sources (100–300 GHz). The D-band (110 – 170 GHz) was proposed for use in 6G communication systems. Radiofrequency detector diodes in traditional near-field probes cannot operate effectively beyond 110 GHz. This necessitates the development of new sensing...
