Title:
ROTMAN LENS
Document Type and Number:
WIPO Patent Application WO/2013/145858
Kind Code:
A1
Abstract:
A Rotman lens having a ground plate (80) formed by means of an electroconductive member; a dielectric substrate (70) arranged on the ground plate (80); and waveguides (51-56) arranged at positions opposing the ground plate (80) with the dielectric substrate (70) therebetween, and having multiple input ports (11-15) and multiple output ports (41-47). The waveguides guide an input signal, which is input to one input port along the line segment connecting both ends of the multiple output ports (41-47) and the one input port, to the multiple output ports, and the waveguides are arranged within the dielectric substrate (70) such that the waveguides do not interfere with one another, thereby reducing loss in the Rotman lens.
