Dual-frequency patch antennas may provide an alternative to large-bandwidth planar
antennas, in applications in which large bandwidth is really needed for operating at two …

A new patch antenna is analysed which provides dual-frequency operation by means of two
narrow slots close to the patch radiating edges. The two modes of operations show similar …

In this article, a wideband aperture-coupled stacked-patch (ACSP) antenna on a flexible
material for wireless applications at the WR-08 band is presented. It is shown that …

A Multiple Input Multiple Output (MIMO) 4-antenna linear array operating at 28 GHz, 37GHz,
41 GHz and 74 GHz bands for 5G mobile communication is presented. The antenna is …

The microstrip antenna has now reached maturity, wherein only a few mysteries about its
behavior are still undiscovered. The invention of such antennas has been attributed to …

By embedding a pair of properly-bent narrow slots close to the non-radiating edges of a
rectangular microstrip patch, a novel dual-frequency operation of microstrip antennas using …

A differentially fed circular patch antenna working in TM 11 and TM 12 modes is proposed
for dual-band high-gain and stable radiation patterns. A set of shorting pins are loaded in …

A novel dual-frequency rectangular microstrip antenna with a pair of step-slots embedded
close to the non-radiating edges is proposed and experimentally studied. The two operating …

A low-profile aperture-coupled microstrip patch antenna (MPA) under multiresonant modes
for wide half-power beamwidth (HPBW), high gain and enhanced-bandwidth is proposed …

Single‐feed dual‐frequency operation of a rectangular microstrip antenna with a pair of spur
lines at the nonradiating edges and an integrated reactive loading at one of the radiating …
