  • Abstract
    The scattering parameters of finite-length MS/NRI coupled-line couplers are derived analytically using coupled-mode theory. Harnessing this theory, a -25 dB high-directivity planar coupler is designed and tested experimentally having a directivity around 35 dB over a 100 MHz bandwidth centered at 1.75 GHz
