Massive multiple input and multiple output (MIMO) has attracted significant interests in both
academia and industry. It has been considered as one of most promising technologies for …

In this paper, the design and experimental validation of a novel miniaturized dual-band dual-
circularly polarized (CP) metasurface (MS) antenna is reported. The proposed antenna is …

This communication presents a multi-band, circularly polarized (CP), wide beamwidth,
highly efficient antenna for use in global positioning systems (GPS). The primary radiating …

This communication presents a single-feed ultra-wideband circularly polarized (CP) antenna
with high front-to-back ratio (FBR). The antenna is composed of two orthogonally placed …

Abstract A compact Microstrip-Line-Fed stacked patch antenna is proposed for
WLAN/WiMax applications. A circular shaped defect is embedded in the ground plane and …

This book focuses on the key technologies, challenges, and research directions of the
Industrial Internet of Things (IIoT). It provides a basis for discussing open principles …

A multiband fractal co-planar waveguide (CPW)-fed slot antenna loaded with a dielectric
resonator conforming to multiple wireless standards is presented in this paper. The …

A microstrip line fed rectangular patch antenna with slots in the patch radiator is designed to
realise triple resonant frequencies with satisfactory impedance matching (| S11|≤− 10 dB) at …

This paper presents a compact 0.92/2.45-GHz dual-band directional circularly polarized
(CP) microstrip antenna for handheld radio-frequency identification (RFID) reader …

A coaxial probe-fed sector shaped patch antenna with the three corners truncated generates
a triple band resonance by employing the higher order modes of the patch. A fourth sectoral …
