Hi there. I'm working on my Final Project about Microstrip Bandpass Filter at 2.4GHz. I'm new in microstrip. Currently, I've done the design and simulation using cst. I notice that the performance of my filter is improving if I shorten the gap of my feed line. I want to ask, what is the effect of varying the length of the feed line. I just can't figure out the reason. I also already tried to left no gap between my feed line and I still can't figure out the reason. I hope anyone with experience and knowledge can help me. Thanks in advance.
