Dielectric Conductivity

This paper is to study the dielectric properties, magnetic properties, and dielectric conductivity of Multi-walled carbon nanotubes (MWCNTs) and polyester (PE) composites. The composites with different amount of MWCNTs (5-15%) have been studied in the Ku-Band range (12.4-18 GHz). The rectangular waveguide (WR-62) was used to measure the dielectric properties and magnetic properties of the samples. The results show the dielectric properties and conductivity of MWCNTs/PE composites is increasing with the MWCNTs filler increases. The real part of dielectric properties values increase from 5.5 to 26.6 with increasing the MWCNTs loading from 5 % to 15 %. The increasing of MWCNTs filler in the MWCNTs/PE composites does not effects on magnetic properties, the real part and imaginary part of magnetic properties are approximate to 1 and 0. The highest conductivity of 15 % MWCNTs loading is reach to 11.02 (S/m) at 18 GHz. Keywords: composites, dielectric properties, magnetic properties, conductivity

Ku Band

A planar power divider operating over the whole Ku-band is presented. The proposed device utilizes a T-microstrip junction combined with defected ground structure and an elliptical patch at the centre of the T-junction. An isolation resistor is connected across the slotted ground plane. The simulated results of the divider show equal power split, insertion loss is less than 0.3dB, return loss of all ports are better than 15dB, and isolation is better than 15dB over the whole Ku-band.

A magnetic-controlled detection system, with a rectangular solenoid coil in a waveguide test fixture, is proposed for radar absorbing coatings. By applying Ku-band rectangular waveguide, the field patterns at different positions, the reflection coefficient S11 and its variation of several coating samples are simulated and measured under current loaded from 0 to 1.0 A. The results show that this detection system is repeatable and stable, and also reliable with the error of less than 10%.
