Abstract

Abstract

The selection of medium material and the parameter design has the key influence on the loss of pulse transmission line. According to distributed parameter theory and electromagnetic microwave theory, the computing formulas of loss of epoxy-glass-fiber (FR-4) and Polytetrafluoroethylene (F4B) materials are given. When the characteristic impedance of microstrip is 50 W and the operating frequency is 10 GHz, the attenuation factor of medium of FR-4 and F4B materials are respectively 0.095dB/cm and 0.0023dB/cm. When the thickness of microstrip is 18 mm and the thickness of medium is 0.25 mm, the attenuation factor of conductor of FR-4 and F4B materials are respectively 0.049 9 dB/cm and 0.035 7 dB/cm. The numerical computing and simulation results show that the loss of medium and conductor of
