ABSTRACT:
A suspended substrate coupler for operation at frequencies of 26 GHz or higher operated in a forward coupling mode. Coupling tends to improve with increased frequency and coupling as tight as 2 dB is provided for frequencies of 40 to 60 GHz. The first and second coupled lines are suspended striplines provided on both surfaces of a dielectric supported between two parallel ground planes. The spacing between the coupled striplines is approximately an order of magnitude greater than the spacing between the coupled lines of a conventional contra-directional coupler, and the length of the coupled sections of the striplines is not required to be a multiple of a quarter wavelength.
