A Review of Performance Characteristics of a Micro-strip Line

Abstract

The basic characteristics of a micro-strip feed line for microwave patch element is studied and presented. The studied line is a straight rectangular shaped micro -strip line designed by Low Temperature Cofired Ceramics (LTCC) as a substrate and copper as the transmission line. A proposed method have been proposed for fabricating the LTCC tape, and the microstrip characteristics such as characteristic impedance which is found by mathematical equations to have a negative and non linear relationship with the width of the microstrip line. Also the transmission line losses are studied by interpreting the effect of the simulated geometry with mathematical model equation, the result for the study was interpreted and conclusions drawn. The effect of frequency on the microstrip was also studied by simulating the microstrip geometry. The result obtained gives a better understanding on general performance characteristic of a micro-strip line. The line is simulated using Comsol.
