A Survey on Compact Modified Dumbbell-Shaped DGS Having Square Loops

S Yang

A compact modified dumbbell-shaped DGS (CM-DGS) on coplanar waveguide has two square loops. The small loop is inside the large loop. To further decrease the resonant frequency of this CM-DGS, a third square loop is embedded inside the small square loop and connected to the edge of this small square loop. The overall signal path is extended by the third loop. Simulation of the proposed DGS shows a lower resonant frequency and hence a size reduction effect.
