UWB Pulse Decomposition in Simple Printed Structures

摘要

The paper describes the ultra-wideband (UWB) pulse decomposition in simple printed structures aimed at low-cost and effective protection. The structure of an asymmetrical modal filter without resistors is considered, and the possibility of the attenuation by a factor of 55 is shown. Another structure—a turn of a meander line (ML)—is described, and the possibility of the attenuation by a factor of 2.5 is shown. Simulations without and with frequency-dependent losses in conductors and dielectrics are compared with experimental results. Based on the described principles, new devices can be designed which will be reliable, cheap, and radiation resistant due to the absence of any lumped components.
