A quarter-mode substrate integrated waveguide (QMSIW) which is the quadrant sector of a
square waveguide resonator is proposed and investigated in this paper. The QMSIW is …

The use of substrate integrated waveguides (SIW) for microwave and millimeter wave
integrated components has increased dramatically over the last decade. They mimic the …

For many leaky-wave antennas (LWAs), it is challenging to realize beam scanning through
broadside. A problem is the presence of an open stopband (OSB), which restricts radiation …

This paper presents a novel, easy-to-fabricate and operate, single-layer leaky-wave antenna
(LWA) that is capable of digitally steering its beam at fixed frequency using only two values …

An isosceles right triangular waveguide with one electric wall and two magnetic walls is
proposed to design a triple-mode filter implemented in a substrate integrated waveguide …

A compact composite right/left-handed (CRLH)-based dualband rectenna is proposed for
electromagnetic (EM) energy harvesting at the operating frequencies of Wi-Fi (2.5 GHz) and …

Wideband microstrip leaky-wave antennas (LWAs) that radiate two symmetrical side beams
are described. The two beams are steered simultaneously by sweeping the operating …

Half-width microstrip leaky-wave antennas (HW-MLWAs) are generally single band. Here,
we present a new method to achieve dual-band operation from an HW-MLWA by …

A composite right/left-handed (CRLH) leaky-wave antenna (LWA) can effectively scan the
radiation beam from backward-to-forward direction. However, in most cases, a large range …

A simple single-layer reconfigurable leaky-wave antenna (LWA) is presented that has
polarization agility and beam-scanning functionality. This LWA system realizes a scanned …
