Abstract
This distributed constant type electromagnetic delay line has an elongated bobbin which includes, laminated together, a substantially rectangular dielectric layer and a substantially rectangular ground plane, and further includes an electroconductive strip, constituted by a single layer solenoid fixedly secured to the bobbin by its outer surface. As a variation, this distributed constant type electromagnetic delay line may have an elongated bobbin which includes, laminated together: a first substantially rectangular dielectric layer; a second substantially rectangular dielectric layer; and a substantially rectangular ground plane sandwiched between the first and second dielectric layers; and may further include an electroconductive strip, constituted by a single layer solenoid fixedly secured to the bobbin and wound in a spaced manner around the outer surface of the bobbin confronting the ground plane.
