Abstract
With the development of stealth technology,the radar cross section reduction( RCSR) of antenna is the key to realize the low scattering platform. The skin antenna is an important technique of antenna RC-SR,and the cavity scattering is a problem which is hard to be avoided,the RCSR of dielectric cavity is an important guarantee for the realization of low RCS antenna. Through studing the scattering properties of cavity,dielectric and dielectric cavity by simulation software FEKO,this paper obtaines the variation law of dielectric cavity scattering with depth and presents the design method of a dielectric cavity with low RCS value. The method utilizes the characteristics that the antenna ’ s voltage standing wave ratio ( VSWR ) bandwidth and RCS of the dielectric cavity monotonously change with the height of the dielectirc,and ac-cording to VSWR bandwidth requirements of the antenna,realizes the RCSR by minimizing the dielectric substrate thickness. The experimental result proves that by using the proposed method,the RCSR of the di-electric cavity is close to 10 dB.关键词
