Abstract
A new method of a dual-hand miniaturized branch-line coupler (BLC) is presented with two widely separated bands (f(2) > 2f(1)) for wireless local area network application. Partially meandered lines are used as the coupler's shunt arms; and are designed to operate at f(1), = 2.45 GHz and f(2) = 5.8 GHz. There are 65 and 90% reduction in circuit area compared to the previous research design. The output signal ports have an equal power split within measurement accuracy and 2 error at the resonant frequencies. The simulated and measured results are in good agreement, thereby verifying the design concept. (C) 2011 Wiley Periodicals, Inc.
