MINIATURIZED ZERO-ORDER-RESONANT METAMATERIAL BANDPASS FILTER FOR THE UWB LOWER-HALF-BAND WITH OPEN-STUB INSERTED NON-UNIFORM INTERDIGITAL COUPLED LINES

摘要

The present invention relates to a bandpass filter for a lower half-band that can be applied to an ultra-wideband (UWB) transceiver, and more particularly, to a left-handed transmission line. A bandpass filter designed using a composite structure with hand-handed characteristics.Non-Uniform interdigital coupling line with an open stub to design a miniature bandpass filter. It utilizes the infinite wavelength characteristics of the zero-order resonator of the transmission line (CRLH), which combines right- and left-hand propagation based on (Interdigital Coupled Lines), and a notch is mounted on the outside of the resonator to implement the bandpass characteristics that meet the specifications.
