| Popis: | This paper proposes a novel technique to miniaturize the size of any reactance-to-reactance transformers (RRTs). These transformers are designed based on conjugately characteristic-impedance transmission lines (CCITLs) and Meta-Smith charts (MSCs). Note that the proposed technique can be effectively applied to popular microwave circuits; i.e., open-circuited and short-circuited tuning stubs as special cases. Numerical results are calculated, analyzed and compared with those of conventional stubs. In addition, the RRT prototype based on CCITLs is designed, simulated and measured to verify the proposed technique. It is found that the properly designed RRT prototype based on CCITLs can provide shorter electrical and physical lengths than those of the conventional RRT prototype indeed. |
