Description
Summary:In this paper a microstrip antenna with substrate constituted by knitted fabrics based on biodegradable synthetic fibers is analyzed. The knitted structure used was jersey composed by polypropylene and polylactic acid from corn. The physical characteristics (yarn count, weight, thickness, dimensional stability and tensile strength) of the knitted fabrics were obtained according to technical norms. The dielectric constant and the loss tangent of the substrate were obtained using the coaxial probe method. Based on results obtained from the simulation, one prototype of the microstrip antenna with rectangular patch was manufacture and tested. The results for the return loss measured from prototype were compared with the simulations. The microstrip antenna proposed resounded below −10 dB in 2.5 GHz with bandwidth of 70 MHz (2.8%).
