Design of Low-Profile Multi-Band Microwave Antennas and Components Using Metamaterial-Based Electromagnetic Bandgap Structures
DownloadSpring 2023
This thesis investigates applications of metamaterial-based electromagnetic bandgap structures, or MTM-EBGs. MTM-EBGs are uniplanar, compact, and often fully printable, making them ideal candidates for integration into planar topologies. This differs from many other metamaterial-based structures...
