Single parallel stubs as broadband microwave phase shifters

Metrology and Measurement Systems, 2020
Structures and characteristics of wideband small-size phase shifters made with the use of single parallel stubsare presented in this paper. The stubs can be short-circuited or open-circuited on termination.
