Extended Composite Right/Left-Handed Transmission Line and Dual-Band Reactance Transformation
Journal of Electrical and Computer Engineering, 2010 An extended composite right/left-handed transmission line is introduced, and its dual-band bandpass filter characteristics are explored. Novel reactance transformations, derived from this transmission line, are formulated to transform a low-pass ...

Improvement of transmission characteristics in multilayer dual band filter [PDF]
2017 IEEE Asia Pacific Microwave Conference (APMC), 2017 This paper first simplify a filter structure optimized by GA. Then the filter structure is modified by introducing slot and stubs, based on magnetic currents at resonant points and transmission zero point. As a result, return loss in two passband regions is suppressed more than 25 dB, and insertion loss in stopband dividing two passbands is suppressed ...

Clutter Mitigation Based on Spectral Depolarization Ratio for Dual-Polarization Weather Radars
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 In this article, a spectral polarimetric filter named moving spectral depolarization ratio (MsDR) filter is proposed to mitigate the effects of clutter and noise for dual-polarization weather radar without cross-polar measurements. The filter is based on

Dual-Band Patch Antenna With Filtering Performance and Harmonic Suppression [PDF]
IEEE Transactions on Antennas and Propagation, 2016 A novel design of dual-band antenna with integrated filtering performance is proposed. A low-profile aperture-coupled U-slot patch antenna is employed for dual-band operation with a uniform polarization, which is fed by a dual-mode stub-loaded resonator (SLR).
