Abstract

In this paper, a novel multi-standard filter with the size of only 4.6mm×41.65mm and a thickness of 0.635mm is presented. This filter is capable of generating two wide operating bands that effectively cover the GSM/UMTS/GPS/IEEE 802.11a operations in mobile devices, which include GSM1800 (1710–1880MHz), GSM1900 (1850–1990 MHz), UMTS (1920–2170 MHz), GPS (frequency band cantered at 5.75GHz) and IEEE 802.11a (frequency band cantered at 5.8GHz) bands. The proposed multi-standard filter’s wide bandwidths at the low and high frequency are attributed to the mutual coupling of the modified SIR resonators. Meanwhile, in band and out of band performances of the proposed filter are enhanced by novel folded structure and even and odd phase velocity compensation technique using shifted coupled lines. Because there is no via hole or defect ground structure included in the filter structure, the structure is relatively simple and easily realized.
