Abstract
A new UWB filter is proposed. The filter structure is based on identical lines and short circuited stubs. The merit of the proposed structure lies in the ability to design a simple structure with arbitrary bandwidth. The proposed filter can be designed for a fractional bandwidth from 40% to more than 100%. The concept is validated through the design of a bandpass filter to cover the entire band of the UWB standard and another filter is designed to cover few groups of the UWB standard (from 6 to 10 GHz). Simulations have been performed using IE3D software package.
