Abstract
This paper introduces the design of low pass filter for radar applications. The main block of the proposed filter is the combination of defected microstrip structure (DMS), compensated microstrip capacitors, and two defected ground structures (DGS). The proposed filter has several desirable features such as low insertion loss of 0.3 dB within the pass band, a wide rejection band from 1.5 GHz to 8.3 GHz with more than 20 dB attenuation, as well as sharp cutoff. Moreover, the proposed design has a compact size of 5.8cm×3.5cm. Experimental measurements of the fabricated filter agree with simulation results, which confirm that the proposed DMS/DGS filter design is suitable for radar and microwave applications.
