Claim:
1. A tapered airline directional coupler comprising: a housing having a length with an input end and an output end disposed at opposite ends of the length, the housing having a slot formed therein extending between the input end and the output end, wherein a cross-sectional area of the slot varies depending upon where the cross-section is taken along the length of the housing; a main conductor disposed within the slot and extending between the input end and the output end of the housing, the main conductor being in electrical communication with an input port connector mounted on the housing at the input end thereof and with an output port connector mounted on the housing at the output end thereof, the main conductor having a cross-sectional area that varies depending upon where the cross-section is taken along the length of the housing; and a coupled conductor disposed within the slot and spaced apart from the main conductor, the coupled conductor being in electrical communication with and extending between a forward coupling port connector mounted on the housing adjacent to the input end thereof and a reverse coupling port connector mounted on the housing adjacent to the output end thereof, the coupled conductor having a cross-sectional area that varies depending upon where the cross-section is taken along the length of the housing.
