| Abstract | ||
| Abstract A parallel-coupled band pass filter is presented in this work. The filter was designed at center frequency of 2GHz, on two different substrate (r=9) and (r=16) with thickness (h=0.635mm). A brief description of design calculation steps is also included. Filter's response is characterized and their performance was compared from the output results like insertion loss, VSWR and bandwidth frequency. The Insertion loss and VSWR for substrate (r=9) were (-1.24dB) and (1.5dB) respectively and the bandwidth was (960MHz). Where for (r=16) the output results were to (-2.8dB), (2.5dB) and (800MHz) respectively. The Q-factor and filters size were reduces as r and electrical losses increases for a certain filter design. | ||
