Investigation of effects of plasma sheath on antenna radiation based on ray tracing method
Source abstract
Abstract
The reason for communication blackout in hypersonic vehicles is strong interference from the plasma sheath on antenna radiation. This paper presents the calculation of the effects of a plasma sheath on microstrip antenna radiation using the ray tracing method, a method comprising an accurate and complex theoretical algorithm. Using an integrated model of a plasma sheath and microstrip antenna, the ray tracing method is used to obtain the disturbed electric field in the sheath with different parameters. This study reveals that the sensitivity of X-band antenna radiation to the alteration of plasma parameters is lower than that of C-band antenna radiation. These numerical results provide a reference guide for the design of antennas for use in hypersonic vehicles.
