IMPACT OF ERROR IN PCB MANUFACTURING TECHNOLOGY ON QUALITY OF RF MICROSTRIP TRANSMISSION LINE

Abstract

This paper presents a study on the impact of the error in PCB manufacturing technology on the quality of RF microstrip transmission line. Therefore, a technology selective process has been proposed based on the theory of allowable errors with the coefficient of the microstrip line structure-material parameters and the manufacturing errors. In this paper, designs of a wideband omnidirectional microstrip antenna (operating frequency from 2.4 to 5.8 GHz) and a RF filter (central frequency is 9.2 GHz) are also investigated. Measurements are carried out on samples after fabrication. Measurement results are compared with simulation results. From there, evaluate the suitability of the selected PCB manufacturing technology for the above designs. The investigation shows that the proposed technology selective process gave appropriate forecast results.
