An analysis of low pass filter using bowtie Defected Ground Structure (DGS) at 10 GHz for radar application

This paper describes the design of Low-pass filter using bowtie Defected Ground Structure (DGS). The designing of low-pass filter begins from lumped element in which the filter will be built using capacitors and inductors before converted to open and short circuited stub. The low-pass filter using bowtie Defected Ground Structure (DGS) is required to operate at 10 GHz for radar application. As a comparison, the design of different size and quantity of bowtie Defected Ground Structure (DGS) were analyzed to identify the better performance of the low-pass filter. The design of this filter had been simulated by using schematic and EM Simulation in Agilent Advanced Design System (ADS) software.
