Abstract :
Microstrip open end (Open) applied as a calibration standard in frequency band up to 26 GHz was analyzed using CST Microwave Studio (CST). Arlon CuClad 233 with thickness 0.508mm was used for simulations. Different lengths of the microstrip lines in front of the Open were considered. Significant influence of the radiated field and the length of the microstrip line on the reflection coefficient magnitude of the standard in the order 0.01 was discovered. Physical explanation of the phenomenon is given.
