Low cost and compact directional coupler for ultrawideband applications
A design of a compact size (35 × 15 mm 2) 3-dB coupler with ultrawideband (UWB) characteristic is demonstrated in this article. The proposed design is accomplished by forming two diamond-shaped microstrip lines that are broadside coupled by a slot at the middle ground plane. The dimension of the des...
