提出了一种新颖的电磁带隙单元结构,具有尺寸小、带宽宽的特点。该元件具有22.8 mm的小单元尺寸,在1.6 GHz处测得的带宽为24%。  一个有用的第二带隙可以实现在2.5 GHz的6%的带宽。 仿真结果表明,在较高介电常数的基板上使用相同的元件尺寸可以在较低的900 MHz GSM频段提供具有足够带宽的带隙。 
A novel electromagnetic bandgap element geometry is presented with compact dimensions and a wide bandwidth. The element has a small cell size of 22.8 mm and a measured bandwidth of 24% at 1.6 GHz. A useful second bandgap can be realised with a bandwidth of 6% at 2.5 GHz. Simulations show that using the same element dimensions on a higher dielectric constant substrate provides a bandgap at the lower 900 MHz GSM band with sufficient bandwidth.
