Compact dual-band power divider based on dual composite right/left-handed transmission line

摘要

A compact dual-band power divider based on a dual composite right/left-handed transmission line is presented. The measured results show that for the presented power divider operating at 1.9 GHz with a 94.2% bandwidth (1.00–2.78 GHz) and at 6.6 GHz with a 12.9% bandwidth (6.25–7.10 GHz), in which the return loss is <–10 dB, the variation of measured Ȣ5;S21Ȣ5; and Ȣ5;S31Ȣ5; is within 3 1; 0.5 dB. Compared with the conventional transmission line power divider operating at 1.9 GHz, the presented one no
