The radial stub as a key microstrip structure to provide low impedance levels with a well‐defined insertion point is proposed. Its characterization through a planar approach provides a superior accuracy, as compared with the simulations attainable from presently available CAD packages. Some experiments have fully confirmed the design. Furthermore, the flexibility of radial lines in replacing both open and shorted straight stubs is demonstrated together with some successful results, achieved through their use in practical applications.
