摘要：

A compact digital phase shifter for an active phased array antenna system is made using folded hybrid coupler. The theoretical analysis is given for the folded structure of branch-fine hybrid coupler. To validate its feasibility, the 4-bit digital phase shifter is designed using commercial simulators and implemented on the Teflon soft substrate (epsilon(r)=2.17). Its circuit size is less than 3.5 cm x 3.0 cm, and it exhibits at least 50% size reduction as compared with the conventional configuration. Its experimental results are also presented.
