The technology described herein is directed towards a wide-bandwidth, high-frequency (e.g., millimeter wave) quadrature coupler. One implementation of the quadrature coupler is passive and compact, is designed with a single top metallization layer, and does not require any interconnecting layer. The planar design can include four ports coupled to the four sides of a rhombus/diamond metal plane portion, with cross-shaped slots that intersect in the center of the metal plane portion for efficiently routing E- and H-fields to other ports. Design tweaks can change the radio frequency (RF) characteristics of the quadrature coupler, including, for example, scaling the quadrature coupler dimensions to establish the center frequency, while retaining constant bandwidth. Other tweaks can be made to the dimensions of the cross-shaped slots. The design facilitates integration with other planar RF technologies.
