Llombart, N. TNO Defensie en Veiligheid Publication year 2006 Abstract This letter discusses the properties of printed antennas whose radiation patterns (their directivity or their shape) are enhanced by means of dielectric superlayers which support leaky waves. In particular the characterizing complex leaky wave poles of the spectral Green Function are approximated analytically, for the first time over large frequency bandwidths. The localization of the poles is a simple mathematical "trick" however, the results provide further physical insigths into wave phenomena that before had to be investigated numerically Subject PhysicsGreen functionsLeaky wave antennasLeaky wave polesDirectivityFrequency band widthGreen functionLeaky wavesPrinted antennaRadiation patternsSuperlayersWave phenomenaWide-bandPolesAntennas To reference this document use: http://resolver.tudelft.nl/uuid:dfe15b78-98de-4a51-bb7b-085997b5b411 DOI https://doi.org/10.1109/lawp.2006.889558 TNO identifier 425214 Source IEEE Antennas and Wireless Propagation Letters, 5 (1), 549-551 Document type article Files To receive the publication files, please send an e-mail request to TNO Library.
