This letter reports a systematic simulation study of the performance of mobile terminal
antennas in the vicinity of the user's hand. The effects of antenna dimensioning and antenna …

Performance and characterization of harmonic transponders is investigated both theoretically
and experimentally. The harmonic response of a transponder based on a Schottky diode is …

This article presents a dual-band, dual-polarized antenna operating from 24 up to 40 GHz at
5G new radio (NR) millimeter-wave (mm-Wave) Frequency Range 2 (FR2) bands. A novel …

Sub-terahertz (THz) frequencies have the potential to realize the extremely high data rates
envisioned for upcoming sixth generation (6G) wireless communications. Moving to this range …

This article proposes a wideband differentially fed dual-polarized magnetoelectric (ME) dipole
for millimeter-wave (mm-Wave) applications. Various electric and magnetic characteristic …

Implementation of proper wireless links at submillimetre-wave and terahertz (THz) frequencies
requires high-gain antennas. This simulation-based study investigates the performance of …

This work presents a review on the concept of harmonic or secondary radar, where a tag or
transponder is used to respond at a harmonic multiple of the incoming interrogation signal. In …

Design of harmonic transponders is presented in a case when the harmonic operating
frequencies are implemented with a separate matching circuit based on lumped components. The …

Analysis of a self-resonant, dual-frequency-matched antenna is presented. The operating
frequencies of the antenna are harmonically separated, and 1-GHz fundamental and 2-GHz …
