Distributed-element circuits are electrical circuits composed of lengths
of transmission lines or other distributed components. Used mostly at
microwave frequencies, they perform the same functions as conventional
circuits composed of passive components, such as capacitors, inductors,
and transformers. They are made by patterning the conducting medium
itself, rather than connecting pre-manufactured components with the
medium. A major advantage is that they can be produced cheaply on
printed circuit boards for consumer products, such as satellite
television. They are also made in coaxial and waveguide formats for
applications such as radar, satellite communication, and microwave
links. Distributed element circuits were used in radar in World War II,
and later in military, space, and broadcasting infrastructure.
Improvements in materials science led to broader applications, and they
can now be found in domestic products such as satellite dishes and
