In this paper, microstrip structure is developed to realized a. Bandpass filter at 3 GHz of the center frequency with 200 MHz bandwidth. The filter based on the hairpin method with used square groove technique at the resonators. It has compact in the size and also have good responses for insertion loss, return loss and bandwidth. The design methodology is present with design, fabrication and measurement the prototype used VNA. The filter designed for simulation and realization with substrate Roger 4350B with permittivity 3.48, loss tangent 0.0038, and thickness 1.524 mm using five poles resonators. The simulation and optimization is done using ADS 2011. Responses Insertion Loss at 3 GHz -0.7 dB and the Return Loss at -29.9 dB.
