  Abstract

In this research, we suggested a new PBG cell with wide stopband. In order to improve the characteristics of the insertion loss, return loss, and ripple, we used two overlapped cells. One is small cell which is made in inside and the other is large cell which is made in outside. The inner cell stops the high band and the outer cell stops the low band. As a result, the new PBG cell had a wide stop band. Insertion loss was about 40dB in stopband and the ripple, and the return loss was improved. Also, the passband is broaden by employing new PBG cells.
