A novel method allowing for reduction of coupling between vertically placed radiating elements in antenna arrays has been proposed. It has been shown, that appropriate offsetting the antenna array elements from the array symmetry axis allows to improve isolation between adjacent elements, which results in improvement of the obtained radiation pattern. The theoretical investigation has been performed...
In this paper, a miniaturized wideband Marchand balun with separated differential output designed with the use of quasi-lumped element technique has been proposed. The circuit utilizes multi-compensation technique together with folded coupled inductors to obtain high performance and reduced size by appropriate folding of the coupled lines, which partially realize the required compensating elements...
A novel wideband Marchand balun and bow-tie antenna have been proposed for sensor application. The proposed balun has been designed to differentially fed bow-tie antenna and match its differential impedance. The proposed approach has been investigated and verified by electromagnetic calculations and measurements of an exemplary Marchand balun and bow-tie antenna operating at center frequency f0 =...
