Abstract
Printed circuit boards (PCB) are widely used in electronic devices, at low and high frequency applications. Unfortunately, conventional PCBs are basically made from toxic petroleum products. Once they are unusable, they are bound to be thrown away since they are not recyclable or easily decomposed. In solving this problem, a new PCB substrate, which is based on reinforcing natural fiber with thermoplastics, is proposed. Oil palm empty fruit bunch has been chosen as raw material while polypropylene (PP) was added as filler. In modeling the prototype, five different loadings of natural fiber reinforced with different percentages of weight of PP were studied. The reflection method (one-port reflection coefficient method) is employed in measuring the permittivity. The measurement covers permittivity and dielectric loss.
