Analysis of a Metamaterial based Leaky Wave Antenna with Laterally Shielded Planar Technology

In this work, theory and simulations are presented to show the working mechanism of a new tool for analysing leaky-wave radiation from Parallel Plate Waveguide (PPW) which is periodically loaded with planar metallization. This device could be used to construct leaky-wave antennas at microwave and millimetre-wave frequencies. The novelty of this method lies in the incorporation and versatility of Roof-Tops basis functions. This enables one to study complex printed circuits designs. The proposed simulation program is an efficient tool to analyze and design leaky-waves antennas with right or left handed properties.
