摘要
This tunable dual-band phase shifter uses a defected ground structure (DGS) and stubs. Its frequency can be tuned by changing the length and width of the stubs and the dimensions of the DGS. The resulting circuit has improved insertion loss and return loss with reduced phase variation, as verified by measurement.
