  • Abstract
    The letter describes a simple method for improving the directivity of side-coupled microstrip couplers an unmetallised piece of the substrate material is cemented on top of the microstrip structure. The measured directivity ranges from 30 to 40 dB. The couplers are fully compatible with normal microstrip techniques.
