Abstract

Suspending micro strip line method is applied to predict the stop band characteristics of the rectangular spiral EBG structure. Effects of height and width of the suspending micro strip line on stop band data, including center frequency and bandwidth, are considered. To investigate this method in detail, a 5 × 5 mushroom-like EBG structure is fabricated. The measured stop band results are compared with those obtained by FDTD method and HFSS, respectively. Finally, an L-band helix antenna based on the rectangular spiral EBG structure is designed. It is found that the input and radiation performance can be improved.
