Design of High-Gain and Beam Steering Antennas Using a New Planar Folded-Line Metamaterial Structure
Figure 4
(a) FL-LHM antenna model which improves the antenna gain by FL-LHM substrate. The reference antenna makes excitation for FL-LHM substrate. The solid red line represents the forward wave and the dotted blue line indicates the wave reflected at the back FL-LHM. (b) Numerical FL-LHM unit-cell model for simulation.
