Three Dimensional Printed Vertically-Stacked Single-/Multi-Band Coaxial Filters and RF Diplexers

High Power Analysis of Filters and Diplexers

Solution‐Processed Vertically Stacked Complementary Organic Circuits with Inkjet‐Printed Routing

The fabrication and measurements of solution-processed vertically stacked complementary organic field-effect transistors (FETs) with a high static noise margin (SNM) are reported. In the device structure, a bottom-gate p-type organic FET (PFET) is vertically integrated on a top-gate n-type organic FET (NFET) with the gate shared in-between. A new strategy has been proposed to maximize the SNM b...

Design of CMOS Integrated Q-enhanced RF Filters for Multi-Band/Mode Wireless Applications

Recent developments in portable applications and systems have lead to a significant in wireless standards. Therefore, cost efficiency of CMOS technology implementation has been greatly enhanced with the emergence of multi-mode wireless applications. Now multimode/multi-band receivers are designed based on the scheme of reuse[1]-[3]. They avoid using multiple chipsets and can be made tunable whi...

Passive Diplexers and Active Filters based on Metamaterial Particles

Composite transmission lines are one of the main developments in the increasingly popular field of electromagnetic metamaterials, artificial electromagnetic structures with both negative electric permittivity and magnetic permeability (Caloz & Itoh, 2005). These structures present a backward wave or left-handed (LH) propagation instead of the conventional right-handed one. The first experimenta...

Modified U-Slot Stacked Micro-Strip Patch Antenna for Ultra-Wideband Applications in S Band, C Band and X Band

The U-slot micro-strip patch antennas were originally developed for bandwidth broadening applications. This study presents a transmission line feed to modify the U-slot stacked rectangular micro-strip patch antenna for Ultra-Wide Band (UWB) communications. The modified antenna has a U-cut loaded with parallel slits and corner slots and is printed on a dielectric substrate of FR4 with relative p...
