A triple band-notched ultra-wideband (UWB) monopole antenna using a planar electromagnetic bandgap (EBG) design is proposed. The EBG unit cell composed by an Archimedean spiral and inter-digital capacitance demonstrates the notch frequencies. with cells near feed line occupies only 30 × 36 mm2 band-rejection characteristics. three notched bands at 4.2 GHz, 5.2 9.1 GHz can be used in C-band sate...

Mechanical testing of an advanced thermoplastic polyimide (LaRC-SI) with known variations in molecular weight was performed over a range of temperatures below the glass transition temperature. The physical characterization, elastic properties and notched tensile strength were all determined as a function of molecular weight and test temperature. It was shown that notched tensile strength is a ...

A novel compact size ultrawide band planar antenna with notched characteristics is present. The rejection characteristic achieved by loading a pair of metamaterial inspired rectangular split ring resonator (SRR) near the feed line and etching SRR slots on radiating patch. simulated measured results reveal that proposed exhibits impedance bandwidth over (UWB) frequency range from 3.1 to 14 GHz v...
