The structure may include a first stripline including a signal line located between a top dielectric and a bottom dielectric. The top dielectric is in contact with a top ground plane. The bottom dielectric is in contact with a bottom ground plane. The structure may include a second stripline including a signal line located between a top dielectric and a bottom dielectric. The top dielectric is in contact with a top ground plane. The bottom dielectric is in contact with a bottom ground plane. The structure may include a joined portion connecting the first stripline to the second stripline. The joined portion the first stripline includes the bottom ground plane, the bottom dielectric, and at least one signal line. The joined portion the first stripline includes the bottom ground plane, the bottom dielectric, and at least one signal line. ## Claims ### Claim 1 A method of splicing striplines comprising: removing a top groundplane and a top dielectric of a first stripline;
