Abstract
In this article, high-performance compact defective ground technique based microstrip low-pass filter with and without dumble -shaped structure is proposed. By etching of dumble geometry on to ground plane, the presented filter gives a wideband operating frequency and sharp cut at stop band with high attenuation. The presented geometry is designed on software. The simulated outcomes shows that the presented low pass filter has very significant advantages in term of wide band stop band from 2.5 GHz to 6.6 GHz with the S21 much better than −35 dB and the presented LPF can meet the requirements of wireless communication systems and microwave applications with its stated efficiency.
