Multi-band dual-mode antenna tunable matching network for broadband applications

Abstract

We present a multi-band dual-mode tunable matching network for broadband applications. Several architectures based on a low-pass π matching network are discussed, whereas the possibility to insert fixed matching network solutions to relax the design constraints is explored. Different methods to efficiently control the network are also studied. The proposed studies are applied to design of broadband tunable matching network covering both LTE 400MHz and 700/800MHz frequency bands in FDD mode. Finally, simulations are done to demonstrate the obtained performances.
