Abstract

The invention provides a flat-panel passive phased array feed network cable source. The flat-panel passive phased array feed network cable source comprises a power splitter, one or more polarization transformers, a power synthesizer and a flat panel waveguide, which are connected in sequence, wherein each polarization transformer comprises an input end waveguide and an output end waveguide, whichare connected through a cavity. According to the flat-panel passive phased array feed network cable source, the waveguide polarization transformers do not need a rotating device and the structure is compact, so that the length of the transformers can be extremely reduced and the cable source is suitable for standard machining; the structure of the cable source becomes compact; signal leakage is reduced and the bandwidth is improved; the echo loss is better than 20d, and a complete feed signal can be provided for a flat-panel passive phased array antenna.

Description

technical field [0001] The invention belongs to the technical field of phased array antenna feeding, and in particular relates to a flat passive phased array feeding network line source. Background technique [0002] In a flat passive phased array antenna, the line source is the key component of the antenna, and its function is to provide a plane wave from the rectangular waveguide port for the antenna feed. There are several ways to realize the line source. The first is a line excitation source composed of horn antenna reflection feed. Due to the reflection of the wave, it can change the spherical wave into a plane wave. This line excitation source is relatively bulky; the second is to use a convex lens or a flat lens The spherical wave of the antenna is converted into a plane wave, and its linear excitation source is smaller in size and lighter in weight than the first one. However, convex or flat lenses are difficult to process with standard equipment, and adding a matc...
