Resonant cavity antennas (RCAs) are suitable candidates to achieve high-directivity with a
low-cost and easy fabrication process. The stable functionality of the RCAs over different …

A novel technique to design a low-cost frequency-selective surface (FSS) bandpass filter is
presented in this article. Wideband polarization-independent FSS bandpass filters are …

This article reviews the latest developments of beam steering antennas that are entirely
passive to realize interference-free, power-efficient, and highly secured end-to-end wireless …

A continuous beam-steering solution for circularly polarized (CP) radial-line slot array
(RLSA) antennas is presented and demonstrated with a fabricated prototype. The solution is …

A linear polarization conversion coding metasurface (MS) is proposed for the radar cross
section (RCS) reduction of an object. The designed MS has both wideband RCS reduction …

An elegant combination of electric near-field phase transformation technique and
electromagnetic-wave refraction, implemented through a pair of 3D printed dielectric …

This article proposes a hybrid absorptive–diffusive frequency-selective radome (AD-FSR)
that has a broadband transmission window with wide absorption and diffusion bands …

In the near-field meta-steering method, the near electric-field phase distribution is
dynamically altered by rotating a pair of phase-gradient metasurfaces that are typically made …

A narrowband dual-band bandpass filter (BPF) with independently tunable passbands is
presented through a systematic design approach. A size-efficient coupling system is …

This paper presents a very efficient design procedure for a high-performance microstrip
lowpass filter (LPF). Unlike many other sophisticated design methodologies of microstrip …
