Directional couplers in Ultra-Wideband (UWB) High-Voltage (HV) radar systems allow the possibility of using a single antenna for both transmission and reception. In this paper, we continue the development of HV UWB coupled-line directional couplers reported earlier in [1], and first suggested by Baum in [2]. We investigate smoothing the impedance profile, increasing the isolation, and reducing the transmission loss, while maintaining high voltage standoff and high mechanical reliability. Note that a more detailed version of this paper appears in [3]
