In this letter, a new class of wideband phase shifters using parallel-coupled-line resonators is proposed and developed. The proposed phase shifter consists of two distinctive branches: a parallel-coupled-line filter and a reference line section. Compared with its conventional counterpart, this phase shifter has a few advantageous features such as simple …ideal choices. Both are 3 dB couplers, meaning that half of the power should be output at the transmitted and the coupled port each. For wider bandwidths and lower coupling, coupled line couplers are common. Examples of these are the single-section coupled line coupler or the Lange coupler. These couplers use the proximity of the
