Abstract :
The design of multi-hole back-to-back microstrip couplers is described, combining standard design methods initially developed for rectangular waveguide multi-aperture couplers and full wave spectral domain techniques for the planar circuits. The couplers consist of two microstrip lines on different sides of a common ground plane. Coupling is achieved through a number of holes (slots) in the ground plane between both microstrip lines. Theoretical and experimental results of a 8-hole coupler with a coupling value of 3 dB for 5 GHz are presented.<>
