    Novel Compact Reconfigurable Metamaterial Diplexer-Based on RF Switches for Wireless Applications
    (Semarak Ilmu Publishing, 2025-02) Tolba, Youssef Khaled; Daw, Ahmed Fawzy; Esia, Saleh Mohamed
    This paper proposes a novel reconfigurable diplexer design based on metamaterial DCRLH transformer. The D-CRLH concept provides duality in the overall response of the diplexer achieving several bands and reducing the overall size of the diplexer, the novel reconfigurable diplexer size is 39x15mm!. The system achieves reconfigurability by utilizing a PIN-diode RF switching circuit in the D-CRLH load line, allowing for seamless connection and disconnection using a biasing circuit. The novel reconfigurable diplexer offers a wide band of operation of 1GHz to 4GHz with notches to cantered at bands 1.8GHz and 2.6GHz with both notches having suppression band of 300MHz. The reconfigurable diplexer covers commercially used wireless bands, making it suitable for diverse wireless communication applications.
