DESIGN OF MICROSTRIP BANDPASS FILTER

Bandpass filters have a big role in wireless communication systems. This electronic device is widely used in the wireless transmitters and receivers. The function of filter in the transmitter is to limit the bandwidth of the output signal to the minimum necessary to convey data at desired speed and in the desired form. Meanwhile, in a receiver, a bandpass filter will only allows signals that want to be heard at the selected bandwidth of the frequencies and reject the unwanted signal to pass through it. A bandpass filter also optimizes the signal-to-noise ratio at a receiver. In designing of microstrip bandpass filters, firstly the approximated calculation based on the concentrated components like inductors and capacitors need to be done before the project going further. In this project, we will design the bandpass filters using the parallel-coupled technique.
