Abstract :
A novel structure for an NRD-guide directional coupler which combines two NRD guides and a dielectric slab is described. The coupling energy is carried by a leaky wave. Two different structures have been made and measured. For the first structure, a dielectric slab is placed between two NRD-guides. For the second structure, the space between the lower and the upper metal plates is completely filled by Teflon. The field along the NRS-guide is measured at Ka-band (35 GHz) and compared with the theoretical results that have been obtained.<>
