Metamaterials are materials typically engineered with novel or artificial structures to produce
electromagnetic properties that are unusual or difficult to obtain in nature. Because of their …

A variety of antennas have been engineered with metamaterials (MTMs) and metamaterial-
inspired constructs to improve their performance characteristics. Examples include …

This paper presents an in-depth review of the performance improvement of antennas using
metasurface. Metasurface is a periodic arrangement of perfect electric conductors (PECs) on …

A simple multiband metamaterial-loaded monopole antenna suitable for wireless local area
network (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) applications …

To maintain the compactness of future 5G smartphones, integration of sub-6 GHz and
millimeter-wave (mm-wave) bands is a challenging task due to the large frequency ratio. We …

Deliberately created defects in the form of etchedout patterns on the ground plane of
microstrip circuits and transmission lines have been familiar to microwave engineers for a …

A dual-layer electromagnetic band-gap (EBG) mushroom structure is proposed in this paper.
Based on the concept of slow-wave propagation, this structure can reduce the size of multi …

In this letter, a novel compact printed antenna for triple-band WLAN/WiMAX applications is
presented. The proposed antenna consists of three simple circular-arc-shaped strips, whose …
