Abstract
Dual-band and multi-band radiating elements are described based on composite right/left-handed (CRLH) meta-material transmission line (TL). These elements can operate as resonators and/or antennas depending on feed-line configuration. The radiating elements are based on the fundamental backward wave supported by a composite right/left-handed (CRLH) meta-material transmission line (TL). Unit-cells of the transmission line comprise conductive patches coupled through vias to a ground plane. The physical size and operational frequencies of the radiating element is determined by the unit cell of the CRLH meta-material. This radiating element is configured for monopolar radiation at a first resonant frequency and patch-like radiation at a second resonant frequency. The first and second resonant frequencies are not constrained to a harmonic relationship.
