dc.description.abstractIn this communication, a novel quad-band rat-race coupler (RRC) is developed for GSM/WiMAX/WLAN/Satellite applications. A conventional RRC is converted to exhibit quad-band operation by using a quad-band microstrip-line (QBML). The proposed QBML is constructed by two coupled-lines, one series transmission-line and two short-ended stubs. The ABCD matrix method is applied to develop the design formulas. Based on these formulas, a quad-band RRC operating at 1.8 GHz, 3.5 GHz, 5.4 GHz, and 7.1 GHz is designed and verified through fabrication and measurement. The measurement and full-wave simulation responses are very much consistent as expected.en
