摘要: In this letter, two types of compact low-loss monolithic coplanar waveguide (CPW) filters using air-gap overlay structures are presented. Vertical stacking in offers size reduction. Furthermore, do not require additional dielectric process and free from losses. An X-band bandpass filter overlaid artificial transmission lines showed 67% A stepped-impedance low-pass highly separated metal-air-metal (MAM) capacitors as low-impedance achieved only but also loss Small size, low loss, simple steps make the very promising for CPW passive devices such filters.
