Abstract

A novel low pass filter using sun-shaped resonator is designed in this paper. The filter is designed by etching the sun shaped resonator on the ground plane and the stub loaded micro strip line on top of the surface. The new sun-shaped resonator is used for reduction in size of filter and to improve electrical performance. The design and simulation has been done using CST microwave studio. Also, the extraction of effective material parameters from the reflection and transmission coefficients is done using Nicolson Ross Weir (NRW) method. The designed filter is also fabricated on the FR-4 substrate with dielectric constant (∈r) = 4.3, height h =1.6mm and thickness of the micro strip conductor t = 0.035mm.The whole area of the proposed filter is 40x48mm2. The low pass filter has a cut off frequency = 1.69 GHz with the insertion loss = -0.3dB. A low pass filter having low pass band insertion loss is proposed. Fabricated and simulated design results shows good agreement.
