A Compact UWB Band Pass Filter Using Simple Defected Ground Structures
By
Progress In Electromagnetics Research Letters, Vol. 79, 17-24, 2018
Abstract
In this paper an ultra-wideband band (UWB) pass filter is introduced. The filter is composed of multiple shorted shunt stubs and defected ground structure (DGS). The defected ground structure is composed of some circular-shape defects and diagonal-line patterns. The bend-shaped defected-ground structure is thoroughly studied and compared to some other defected structures. The filter features a simple structure and small dimensions (12 × 22 mm2). Meanwhile, a systematic design method is presented. The analysis method is based on numerical methods and is verified by a commercially available EM simulator. The 3 dB passband of the proposed wide band filter is between 2 GHz and 10 GHz.
