Abstract:
1. A matrix switch comprising: a plurality of 1×n switches which are grouped in twos to form switch pairs where n is an even number not less than 4; first conductive lines arranged to connect the two switches of each switch pair via n first conductive lines; n second conductive lines which respectively connect to different lines of said first conductive lines which are respectively arranged on the switch pairs, so that one each of the first conductive lines of each switch pair is connected to one each of the first conductive lines of all other switch pairs; a dielectric layer with a multi-layer structure on which said first conductive lines and said second conductive lines are separately arranged on not less than two layers of the multi-layer structure; and a ground conductor which forms a transmission line together with at least one of said first conductive lines and said second conductive lines and said dielectric layer, wherein each said 1×n switch comprises one common terminal and n individual terminals arranged on a side different from that of the common terminal, each said two 1×n switches forming the switch pair are disposed such that individual terminals of 1×n switches are spaced apart from each other to face each other, said first conductive lines connect the respective individual terminals of each said two 1×n switches to each other, where the matrix switch further comprises:
