A new miniaturized dominant mode leaky-wave antenna is proposed. This antenna is a transmission line structure with radiating wavenumber increasing from negative to positive values, providing backward to forward scanning capability as frequency is increased. The antenna profile is designed based on microstrip technology using balanced composite right left handed transmission lines (CRLH TL) app...

Introduction In this contribution, we present a multi-channel T/R coil for use in a 9.4T animal scanner system. Each coil element comprises a composite right/left-handed (CRLH) metamaterial transmission line (MTL). Eight of these elements were arranged in a circular manner to constitute a multi channel coil. MTLs offer the feature of a homogenous current distribution along the line when they ar...
