| Directional couplers are the key elements in many wideband millimeter wave systems. In this case, the coupler must provide a broadband flat frequency response to another millimeter wave circuit. Therefore, two types of directional couplers have been designed in order to achieve a constant level of weak coupling over a wide frequency band from 20 to 40 GHz. The fist one was obtained by employing two cascaded sections, one of which, has a wiggly (sawtooth) conductor-edge geometry between adjacent conductors. The second one is a nonuniform coupler. Both couplers were implemented in microstrip technology on alumina substrate. Results of measurements are also presented in this paper. | |
