Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0027] Such as figure 1 as shown, figure 1 It is a schematic diagram of the curved edge and vacant port of the traditional Rotman lens, where 1 is the peripheral outline of the traditional Rotman lens, and 2 is the vacant port on the side of the traditional Rotman lens; in order to achieve better absorbing effect, the vacant port The end of the lens usually needs to be connected to a resistive load (or absorbing material) 3; in this case, due to the resistance value error of the resistive load or the error in the amount of absorbing material applied, it will affect the consistency of lens manufacturing and performance, and at the same time It also increases the complexity of manufacturing.

[0028] Such as figure 2 as...

Abstract

The invention discloses a Rotman lens with an elliptical-profiled side edge. The Rotman lens comprises a high-frequency insulation substrate, a ground-covering plane formed at the lower surface of the substrate and a metal material planarization lens formed at the upper surface of the substrate. The metal material planarization lens comprises an input port, an output port and the elliptical-profiled side edge disposed between the input port and the output port. The input port comprises a plurality of signal input ports and a plurality of vacant input ports. The output port comprises a plurality of signal output ports and a plurality of vacant output ports. The side edge of the metal material planarization lens is not provided with a vacant port connected with a resistive load. According to the invention, an elliptical side contour is used for replacing a conventional side edge, and the side edge is designed to be the vacant port connected with the load, such that the manufacturing convenience, consistency and reliability of the Rotman lens are improved, and the Rotman lens provided by the invention is suitable for batch manufacture and production.

Description

technical field [0001] The invention relates to the technical field of integrated phase-shifting devices and integrated phase-shifting networks, in particular to a Rotman lens with an elliptical profile on the side. Background technique [0002] In modern radar and communication systems, antennas are often required to have beam steering functions and multi-beam characteristics. The multi-beam antenna can form a high-gain sharp antenna beam to achieve ultra-long working distance; it can also change a single fan-shaped working area into a fan-shaped area composed of multiple sharp beams, and realize wide-angle and long-distance detection range at the same time; In addition, by controlling the phase and amplitude of the feed-in signal, the suppression of interference signals in a particular direction can be achieved, so it also has the ability to suppress interference. [0003] There are two ways for the antenna to complete multi-beam forming and scanning: phased array antenna...
