A reconfigurable dual-band antenna with pattern diversity is proposed. By switching the
dispersion curve of a composite right-/left-handed transmission-line-inspired structure, the …

This article presents a design technique of quasi-elliptic filters by applying two novel planar
triplets, which eliminates the need for negative couplings. A composite right-/left-handed …

Two small multifunctional antennas based on the negative order resonance (NOR) are
proposed for the 5G new radio (N78 band) application in this article. A novel ring-type …

This article demonstrates a new design concept of 3-D printed multilayer vertically integrated
composite right/left-handed (VI-CRLH) transmission lines (TLs) with compact size …

Wearable antennas are increasingly being miniaturized and broadened in terms of
bandwidth due to the increasing need for multi-standard biomedical communication and …

An integrated design of conformal 4G and 5G Multiple-Input Multiple-Output (MIMO) antenna
system is proposed. The 4G MIMO antenna system consists of electrically small two-element …

This study presents a multiband compact microstrip antenna for portable wireless
applications. The proposed antenna, in addition to wireless local area network and a global …

This book discusses antenna designs for handheld devices as well as base stations. The
book serves as a reference and a handy guide for graduate students and PhD students …

The capability of complementary capacitively loaded loop (CCLL) metamaterial (MTM) to
miniaturise printed slot antenna is examined. This study presents a planar compact antenna …

In this paper, a tri-band metamaterial (MTM) loaded compact monopole antenna is
proposed. In the first step of design procedure, a rectangular monopole antenna is improved …
