Abstract :
This paper presented a novel dumb-bell defected ground structure with lengthened etched gap (LDGS), which improved dumb-bell DGS by adding additional etched gap in etched square area. It increases the equivalent parallel capacitance, has a lower resonant frequency. Simulation and measurements results show the resonance frequency of the LDGS is 2.48 GHz, while general dumb-bell DGS is 5.49 GHz with the same area. The method is applied to the design of a low-pass filter to confirm validity of the proposed DGS. The results show that the filter structure has excellent performance.
