Abstract
The performance of a very thin conformal cavity backed slot spiral antenna for various dielectric loadings inside and outside the cavity is considered. An improved FE-BI code is used to numerically predict and estimate the antenna performance for various antenna parameters. Near-field data are used to estimate the miniaturization effects for various dielectric loadings. These data are correlated to the miniaturization effects extracted from the antenna gain. An archimedean slot spiral antenna 15.2 cm in diameter and 1.2 cm thin is designed, built and measured and results are compared to the simulation.
