hi guys, I need to deal with a project regarding an ultra-small microstrip bandpass filter with a new type of capacitive coupled resonator.The filter should be 2 times smaller compared to the smallest known filter of the same class. The filter is designed for high frequency range (Ku band 12-18GHz), therefore the resonant frequency and bandwidth should be in this range. The microstrip used is the Duroid substrate (er = 4.5). Preferably the filter should be designed in a square-shaped form to minimize the space required.Hope you guys could help with some information which would be benefitial for the project.Thank you
