Description
Summary:This paper presents some results of the work done within the frameworks of the ISTC project #B-922. The simulation data and experiments demonstrate possible techniques of improving characteristics of planar ultra-wideband (UWB) antennas based on the tapered slotline. To this end, four ultrawideband baluns, namely the 4 th -order Marchand balun, microstrip to slotline transition with open cavity, two designs of radial stub baluns, and three types of aperture such as exponential Vivaldi type, elliptical flare with corrugated edges and elliptical open flare had been studied. Several planar UWB antennas with dimensions of 23 to 12 centimeters were simulated using electromagnetic simulation software, and then designed, fabricated and tested. The simulation and experimental results on the evaluation of the bandwidth and radiation pattern of the antennas are presented.
