Abstract

In this paper, a novel compact ultra-wideband (UWB, 3.1 GHz-10.6 GHz, defined by U.S. Federal Communications Commission) band-pass filter with good transmission characteristic and flat group delay is presented by using multiple-mode resonator (MMR) and open stubs. The proposed structure consists of a main multiple-mode resonator and four open stubs. The dimension of this structure is 10 mm × 2.2 mm (not including the 50 Ω microstrip), which is much less than conventional structure. By properly optimizing the parameters of the multiple-mode resonator and open stubs, four resonator modes can be allocated within the UWB band. It can cover the frequency band of 3.1 GHz to over 11 GHz and has 3-dB bandwidth of more than 110% that can satisfy the requirement of UWB band communication system.
