Abstract

By the use of screen-printing technique, four kinds of basic structures (outer-frame, U-shaped resonator, modified end-coupled microstrip line, and defected ground structures) are combined to develop a miniature quad-band bandpass filter on a MgTa_1.5Nb_0.5O₆ microwave ceramic substrate. The operating frequencies are designed for the applications of the modern GPS (1.57 GHz), WiMAX (3.5 GHz) and WLAN (2.45/5.2 GHz) systems, and the design procedures are discussed in detail and both of the simulated and measured results are presented.
