摘要： The present application provides a multiplex antenna matching circuit and method for coupling multiple signal ports to an antenna via cascaded diplexers. The multiplex antenna includes a diplexer for coupling a single merged port associated with an antenna with two separated signal nodes. The multiplex antenna further including at least one cascaded sub-diplexer. Each cascaded sub-diplexer is associated with a respective one of the two separated signal nodes, where the cascaded sub-diplexer further couples the respective one of the two separated signal nodes with a respective two further separated signal ports.
