This paper presents a metamaterial approach based ultra-wideband patch antenna using a different split-ring resonator structure. The proposed split-ring resonator is constructed on a 0.43mm thick RT Duroid substrate above a partly covered ground plane. The radiating element comprises of a rectangular geometry with arc-shaped structures at the shorter edges, with an overall dimension of 39x30 mm2. The proposed antenna provides a much favorable radiation pattern with a very efficient impedance matching across a wide bandwidth of 3-44 GHz, making it highly suitable for its operation at and beyond ultra-wideband applications and 5G communications. This paper discusses the antenna's design and the parametrical studies performed using available simulation tools. © 2018 IEEE.

Metamaterial Based Compact Planar Antenna for UWB and 5G Applications

Proceedings - 2nd International Conference on Micro-Electronics and Telecommunication Engineering, ICMETE 2018

The large-signal behavior of traveling wave tube amplifier for a linear beam dielectric loaded anisotropically conducting tape helix slow wave structure (SWS) is realized through a swift and reliable field analysis. Using Green’s function sequence, the field components in the SWS are designated as nonlinear functionals of electron arrival time. The electron arrival time in the beam region is formulated into a nonlinear operator in the Banach space mapping form by substituting the axial electric field component into the electron ballistic equation. The nonlinear beam–wave interaction is then obtained by determining the electron arrival time through extensive successive approximations, and thus exact electric and magnetic field components in the tape helix SWS are attained. The numerical computation of the proposed model yields definitive analytical results for the electron exit velocity, induced surface current density, power gain, conversion efficiency, and optimum interaction length. © 2017 Informa UK Limited, trading as Taylor & Francis Group.
