Abstract :
We investigate the feasibility of CRLH zeroth-order resonant (ZOR) antennas for the 24 GHz ISM band on Rogers RO4350/4450 multi-layer low-cost technology. This technology is used for the first time to implement metal-insulator-metal (MIM) CRLH antennas with its fine metallization features. The fabricated antennas may find applications in the field of automotive or industrial sensors, since the RO4350/4450 laminates are approved for this purpose. The presented return loss and radiation pattern measurements of several prototypes with different length varying from nearly one up to several free space wavelengths indicate that the proposed low-cost implementation is reliable in terms of fabrication and material parameter tolerances.
