Wideband U-Shaped Wearable Antenna With Defected Ground Structure for Biomedical Wearables

International Journal of Antennas and Propagation
This study presents a compact, flexible U-shaped wearable antenna with a defected ground structure (DGS) for biomedical applications. Fabricated on a 1 mm polydimethylsiloxane (PDMS) substrate using conductive adhesive tape, the antenna achieves a wide ...

Distinct Microstructural Characteristic Lengths Defining Notch Fatigue Crack Initiation and Propagation, and Defect Tolerance in Advanced Steels

Advanced Engineering Materials, EarlyView.
Schematic representation of modes of microcrack nucleation, growth and temporary arrestment at different boundaries, with the criteria for crack propagation in three scenarios: (1) large notch, (2) defect/small sharp notch, and (3) long crack. This work revisits and integrates results on the fatigue behavior of advanced bainitic steels (in particular ...

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

Advanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Dual-frequency filtenna using defected ground structure for VSAT applications

, 2014
This paper presents the design of a dual-frequency filtenna using a defected ground structure (DGS). A shared aperture coupled microstrip antenna operating at 20/30 GHz (Ka band) is integrated with a coupled-line bandpass filter to increase the isolation
