UCLA electrical engineers have developed and reduced to practice a conformal composite right/left handed leaky wave antenna which can be mounted on curved surfaces and vehicles, opening up applications in automotive, military, and aerospace industries.
Researchers at UCLA have developed and tested the first conformal CRLH LW antenna, allowing these antennae to be mounted on curved surfaces whereby dispersion engineering was used to compensate for the conformational effect. The conformal CRLH LW structure performs backfire-to-end fire radiation and beam scanning by frequency tuning. Furthermore, varactor diodes can be employed to perform electronic beam scanning at desirable fixed operation frequencies. Lastly, an array factor approach was developed to accurately test and analyze the conformal CRLH LW antenna structure. The novel conformal CRLH LW system was found to be comparable to a conventional planar system in terms of radiation characteristics, bandwidth, and return loss. MORE [2008-215]
