A NEW TYPE OF SLOW-WAVE PBG MICROSTRIP STRUCTURES

Dusan Nesic

Abstract


A new type of 1D slow-wave PBG microstrip structures is introduced. They have no etching in the ground plane and have a simple modification of the microstrip line. The basic cell is applied to three different structures. They all exhibit significant slow-wave effect and the reduction of the lengths is 50% or more. S-parameters are very good and agreement between simulation and measurement is reasonable.
