Based on the traditional serpentine groove waveguide (SGW) slow wave structure (SWS), a novel back-to-back SGW (BTBSGW) is proposed in this article. The BTBSGW maintains the operational mode ...

I. INTRODUCTION. Microstrip antennas are essential elements in wireless communications [].Over the years, new antenna models have emerged, such as parabolic, log-periodic, and Yagi-Uda antennas, ...

In this paper, a flexible tri-band reflective metasurface, the metapocket, is presented to work with smartphone antennas to enhance its realized gain, and radiation efficiency and reduce its Specific ...
