なる構成のアンテナ共用器。 In a case equipped with an input terminal, an output terminal, and an input/output terminal, there are a transmitting filter and a receiving filter, each of which is formed by combining a plurality of resonators, and connected between each filter and one of the above-mentioned terminals. In an antenna duplexer that is used with the input/output terminal connected to a transmitting/receiving antenna, the matching element and the resonator constituting the transmitting filter and the receiving filter are configured to accommodate a matching element. An antenna duplexer having a configuration in which a resonator to be connected is made smaller than other resonators, and the matching element is arranged in a space created by making the resonator smaller.
