Electroacoustic Radiation Characteristics of Circular Sector Microstrip Antenna (CSECMA)

Abstract

Radiation characteristics like radiation pattern, radiation conductance and directive gain of the circular sector microstrip antenna (CSECMA) are studied in the warm plasma medium for two different sector angles and the effect of electroacoustic waves is observed. The current distribution on the patch is determined by using cavity model and image theory. The expressions for antenna parameters in electroacoustic and electromagnetic modes are derived using well established hydrodynamic theory of plasma. The results are computed and plotted for different values of plasma parameter. A significant effect of plasma is noted in both modes.
