Abstract

In this letter, dual band negative group delay circuit (DBNGDC) utilizing a couple of one quarter guided wave length (λg/4) open circuited stubs (OCSs) is presented. The centre frequencies (f01;2) are fully controlled with the stub lengths. On the other hand, the target negative group delay (NGD) is obtained using couple of resistors (R1;2) that connect each OCS to the main microstrip line. The designed DBNGDC accomplishes 52% size diminution compared with smallest size has ever been achieved before. Moreover, 0.2 and 0.4 GHz zero-NGD bandwidths (BW) are achieved.
