Abstract
The investigation of coplanar waveguide fed ultra-wideband antenna and the influence of the proximity of different materials on the reflection coefficients and radiation character-istics is presented. The antenna is composed of two circular coplanar strips which enclose slot aperture of similar shape and is designed on a thin and flexible substrate. From the modeling and experimental tests the antenna shows good performance in 2 - 15GHz frequency range with return losses better than 10dB. It is shown that the proximity of different, non-metalic materials does not significantly affect antenna performance. The proximity of metalic screens deteriorates its radiation pattern and reflection coefficient. However with the correct choice of the distance between screen and antenna the required level of return losses can be provided.
