Abstract
AbstractA Spaceborne broadband circularly polarized conformal antenna for ultra high frequency band is presented. The antenna mounted on the outer surface of the circular arc spherical cone satellite works in 390–450 MHz frequency band, and has the characteristics of broadband, light miniature. The measured results for the antenna demonstrate an impedance bandwidth of 32.5% from 360 to 500 MHz, an axial ratio bandwidth of 27.2% from 380 to 500 MHz, and a peak gain of 6.7 dBic. The antenna form can be applied to the field of broadband circularly polarized conformal antenna on satellite and missile, and has a wide application prospect.
