This paper proposes and develops a novel resonator, which is composed of two strongly-coupled λ/4 sub-resonators via an interdigital capacitor. Firstly, two strongly-coupled Stepped Impedance Resonators (SIRs) are considered as a single resonator and its resonant properties are investigated theoreti...
