Abstract
An impedance adaptor is provided, including first and second transmission lines, each of which is provided by an arm and includes a first conductor and a second conductor. The transmission lines are arranged such that the first conductor of the first transmission line is adjacent and co-planar with the first conductor of the second transmission line, and the second conductor of the first transmission line is adjacent and co-planar with the second conductor of the second transmission line. A first end of the first conductor of the first transmission line is electrically coupled to a first end of the first conductor of the second transmission line. A first end of the second conductor of the first transmission line is electrically coupled to a first end of the second conductor of the second transmission line.
