Showing papers on "Folded inverted conformal antenna published in 1959"
TL;DR: In this paper, a multislot antenna was built, of which the VSWR is smaller than two in the band of 100 to 1000 cm. The principle of this antenna is analogous to the one of pass band filters in which few modes of resonance are possible, appearing one after the other when frequency varies in the frequency.
Abstract: A multislot antenna was built, of which the VSWR is smaller than two in the band of 100 to 1000 mc. The principle of this antenna is analogous to the one of pass band filters in which few modes of resonance are possible, appearing one after the other when frequency varies in the band. While one mode is decreasing and the following is increasing, the simultaneous transmitted waves by the two modes are in quadrature of phase. To do this, it is necessary to have, for each central frequency of the different modes, the radiated electric field on the antenna in the opposite direction with respect to the direction of the electric field for the central frequencies of the two close modes, the direction of the electric field in the feeder being the same in every case.
