Aperture coupling between dielectric image lines
Abstract
Aperture coupling between dielectric image lines is used to develop a design technique for directional couplers at millimeter-wave frequencies. Expressions for coupling coefficients and directivity, employing coupling between image lines through apertures in the common ground plane are developed. The design procedure is illustrated by application to 10-, 20-, and 30-dB directional couplers in rectangular image lines with circular aperture coupling.
