Since its first introduction about a decade ago, the halfmode substrate-integrated waveguide
(HMSIW) has gained enormous interest from researchers, with particular appeal in the …

A frequency-and pattern-reconfigurable two-element array antenna based on a stub-loaded
configuration is presented. The frequency-tuning mechanism is implemented using varactor …

This paper proposes a compact reconfigurable (bandstop/bandpass) and frequency-tunable
structure based on S-shaped split-ring resonators (S-SRRs). It is known that an S-SRR …

A stub-loaded microstrip patch antenna with reconfigurability in both frequency and
polarization is presented. Using 12 varactors with two independent voltages …

A varactor-tunable second-order bandpass frequency-selective surface (FSS) for microwave
frequencies is presented in this article. The FSS is composed of three stacked metallic …

Shorting vias are standard components in planar technologies, but their implementation is
not straightforward in wearable textile electronics technologies. In this article, four different …

A frequency-and pattern-reconfigurable antenna based on a center-shorted microstrip patch
is presented. The novel design utilizes two resonance modes of a microstrip antenna with …

A reconfigurable wearable textile antenna with wide frequency tuning range is demonstrated
in this work. Frequency agility is realized by adding a coplanar reconfiguration module to a …

In this paper, we present a frequency-selective rasorber with tunable transmission window
located within the absorption band. The rasorber maintains a low reflectivity, which is less …

This article introduces a multifunctional polarization insensitive frequency selective rasorber
(MF-FSR) comprised of periodic metallic patterns printed on two dielectric substrates and …
