We report a novel approach for the design of a Butler matrix-type feeding network that allows for achieving two-beam antenna arrays in a very broad frequency range. The proposed solution is based on a 2 × 4 frequency-selective beamforming network wh

In this paper a wideband six-port reflectometer, composed of coupled-line directional couplers is proposed. It is shown that modifications applied to the classic solution have allowed for increasing the operational bandwidth. In addition, the obtaine

In this paper differentially-fed directional couplers have been proposed in which two-conductor balanced lines are arranged vertically. The possible realizable coupling in such structures is investigated and a method for coupling enhancement is propo
