Title
(EN) COMPOSITE RIGHT LEFT HANDED (CRLH) MAGNETO-ELECTRIC UNIT-CELL BASED STRUCTURE FOR ANTENNA AND SYSTEM
Abstract
(EN)

The disclosed systems, structures, and methods are directed to an antenna comprising: a plurality of Composite Right Left Handed (CRLH) magneto-electric unit-cell based structures, each CRLH magneto-electric unit-cell based structure comprising: a ground electrode for common electrical contacts, a first coaxial connector and a second coaxial connector, a first ground surface and a second ground surface, the first ground surface connected to a second end of the first coaxial connector and the second ground surface connected to a second end of the second coaxial connector, a coaxial line included in the second coaxial connector, a microstrip feed line connected to the coaxial line and electromagnetically coupled with the first and the second ground surfaces, and a first non-resonant meta-surface patch and a second non-resonant meta-surface patch, each of the first and second non-resonant meta-surface patches placed above a series-capacitor gap between the first ground surface and the second ground surface.
