The presence of resonant segments leads to the fact that the device has large dimensions at low frequencies of th...

In this paper, an original design of a directional coupler with five connected quarter-wave plumes is proposed. This number of loops allowed to increase the bandwidth of operating frequencies, but at the same time the length of such a device becomes large. This leads to the fact that it is necessary to use more dielectric material on which the micro-plane couplers are made. In order to reduce the cost of manufacturing the device can be used miniaturization of microplane devices. In this article the design of the c...

Directional couplers implemented on two pairwise identical segments of the transmission line, have only one working bandwidth. In order to organize the performance of the structure on two ranges or more, it is necessary to make design changes to the standard device. For example, for operation at two frequencies, idle plumes are added to the design of the coupler. However, this has further increased the dimensions of the coupler, especially at low frequencies, and in some cases the design may be practically unsuita...
