A new shape of defected ground structure (DGS) is introduced. The advantage over conventional dumb-bell shape DGS is, the physical dimensions and frequency response can be directly determined using its equivalent LC circuit. The equations can be extracted from Stepped Impedance Hairpin Resonator (SIHR) low pass filter study. They are similar in term of electrical characteristic. Conventional dumb-bell DGS use iterative trial and error method for the same purpose. It is time consuming and tend to lead to inaccurate design. This new DGS simplify and speed up design process significantly. Measurement and simulation data shows good relationship except at high frequency whereby the measured circuit suffers greater transmission loss. Higher dielectric constant material is suggested to reduce this effect.
