Abstract :
A compact self-packaged dual-band filter structure using multilayer liquid crystal polymer technology is presented in this paper. The frequency and bandwidth of each passband can be more conveniently controlled by means of vertically embedded elements, i.e., metal patches, placed above the coupled folded multi-stepped impedance resonators. The packaged solution is connected to the outer environment through a coplanar waveguide that allows flip-chip interconnection to a host board. The proposed design is validated with the fabrication of two prototypes. The measured results show good agreement with the simulations.
