چکیده مقاله:

In this paper, a novel reconfigurable defected ground structure (DGS) resonator presented on microstrip line technology. Two U-shaped patterned ground microstrip bandstop resonant cells are proposed which enable the generation of multiple transmission zeros at arbitrary frequencies. The number and location of these transmission zeros are controlled by MEMS (Micro-Electro-Mechanical-Systems) Technology for millimetre wave applications. The equivalent circuit of one state is obtained by using a conventional circuit parameter extraction method. Moreover, the slotline design equations are used to identify the transmission zeros and validated using the magnetic field distribution inside the slot. Electromagnetic and equivalent circuit simulated results are in good agreement with each other
