| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This report presents an experimental study on an impact of conductor surface roughness on microwave circuits using thin substrate. As an example of microwave circuits, transmission loss of a microstrip line (MSL) and antenna characteristics of a microstrip antenna (MSA) were evaluated. Three types of substrates using non-, low- and standard roughened copper foils were fabricated. First, the transmission loss of fabricated MSLs were measured, and the loss of the substrate using the non roughened foil was less than half the loss of the substrate using the standard roughened foil. Next, the effective relative conductivity of the fabricated substrates were estimated from the measured loss, and MSAs on the substrates were designed considering the estimated conductivity. As a result, the bandwidth of the fabricated antennas increased due to increasing conductor loss caused by surface roughness of copper foil. Moreover, the gain decrease of 3.6 dB caused by surface roughness have been obtained. |
