Abstract
The technology described herein is directed towards a wide-bandwidth, high-frequency (e.g., millimeter wave) crossover coupler. One implementation of the crossover coupler is designed with a single top metallization layer, is passive, and does not require any interconnecting layer. The design can include cross-shaped apertures enclosed by four metallic inner and outer partial patches, which effectively direct the electromagnetic fields to the crossover circuit's ports. Straightforward design tweaks can change the radio frequency (RF) characteristics of the crossover coupler, including, for example, selecting various design dimensions that determine the center frequency, bandwidth, coupling strength, and/or characteristic impedance of the crossover coupler, and can account for substrate permittivity and the height of the substrate. A cutout in a ground plane beneath the substrate can be sized to mitigate RF mismatch.
