Composite material stripline waveguide array antenna

Abstract

The invention discloses a composite material stripline waveguide array antenna, which is designed on the basis of a novel composite material stripline waveguide and a composite material stripline waveguide radiation unit, and is mainly used in microwave antennas in the field of radar and communication. The composite material stripline waveguide array antenna is made of 13 layers of flat materials, such as an array antenna inner conductor, a feed power divider single-sided copper clad layer, an array antenna outer conductor, a radiation slot speaker array single-sided copper clad layer, a stripline inner film layer, a medium support layer, a reinforcement layer, a stripline outer film layer and the like, with different thicknesses, by high-temperature machining processes of a bag pressing or die pressing method. The composite material stripline waveguide array antenna has the characteristics of low loss, light weight, stable structure, simple machining, low cost, high sealing performance and the like. The machined linear array antenna has the external dimension of 2,400mm*200mm*10.8mm and the weight of only 1.2 kg.

Description

technical field [0001] The invention relates to the field of radar or communication antennas, in particular to a stripline waveguide array antenna of composite material, which is mainly applied to microwave array antenna systems requiring relatively light weight for radar, communication, measurement and astronomical observation. technical background [0002] Microwave transmission lines are divided into coaxial waveguides, rectangular waveguides, circular waveguides, microstrip line waveguides, stripline waveguides and other transmission lines, and different transmission line waveguides are selected according to different application backgrounds. With the development and progress of microwave active device technology and technology, its price has dropped significantly, which has greatly expanded the application range of active devices. The demand for microwave active circuits and microwave active array antennas is strong. , stripline waveguide and other microwave transmissio...
