Compact planar 3-way power divider using left handed transmission lines

In this paper, we propose a three-way planar fork power divider that has its ports located on a straight line. To achieve equal phase output ports, transmission lines are inserted between the fork divider and two of the output ports. To reduce circuit size without the need for meandering, left-handed transmission lines are also used. Simulations of a 3-way microstripline power divider operating at 5 GHz demonstrated that the performance was comparable to a 3-way divider realized from only microstripline, but with a size reduction of 27%.
