, 2014 Wireless communication has become an indispensable part of modern life. One of the mostimportant components of wireless communication systems are antennas, termed as "eyes" and "ears" of communication systems. A printed antenna, one of the most commercial antennas, is widely used for civil and military applications, i.e., for communication systems ...

Tunable High‐Performance Metamaterial Filters Based on Novel SRR Architectures
Advanced Science, EarlyView.Based on two novel SRR configurations and two independent SRR integration approaches, four tunable bandpass metamaterial filters were fabricated with an ultra‐thin ceramic substrate. Among them, SM‐2 achieves over 97% electromagnetic wave transmittance, with a minimal 1.15% deviation in its resonant frequency prediction, making them promising ...
