• Miniaturized Dual-Band Hybrid Couplers With Arbitrary Power Division Ratios (2009, background): “In [3] and [4], a straight line section loaded with a shunt element is proposed to play the role”
• Compact Dual-Band Branch-Line and Rat-Race Couplers With Stepped-Impedance-Stub Lines (2010, background): “The measured bandwidths of dual bands are 13% and 7%, which are slightly wider than coupler . Coupler also performs better than the other couplers in [12], [ 14 ], and [21] in terms of bandwidth.”
