Análisis Preliminar del Strip-slot Complementario en Tecnología Stripline
A stripline-fed slot antenna configuration is proposed using planar technology. Its main advantages are the broad impedance bandwidth available and the radiation in only one half-space, which are obtained with the use of ... -
Application of Huygens’ Metasurfaces to the Arbitrary Design of a Leaky-Wave Antenna
Abdo-Sánchez, María Elena
; Epstein, Ariel; Eleftheriades, George V. (2017-09-13)
Leaky-wave antennas are guiding structures that leak power along their length. Their radiation is mainly characterized by the propagation constant (leakage factor and phase constant) of the traveling wave. In this ... -
