Electroacoustic Radiation Properties of Microstrip Linear Array Antenna on YIG Ferrite

Abstract

In this paper, the electroacoustic (EA) and electromagnetic (EM) characteristics of a four element linear array of circular patch microstrip antenna (CPMA) designed on a typical YIG (Y₃Fe₅O₁₂) ferrite substrate are presented at 10 GHz. The far-zone field expressions for the EM and EA mode are obtained using well established hydrodynamic theory and vector wave function technique. Computation of maximum field intensity, half Power beam width (HPBW) and other important antenna parameter like directive gain, radiation efficiency and conductance has been made for the plasma and the free space medium.

Indexing terms:

• Microstrip array antenna
• Ferrite substrate
• Plasma
• Dielectric substrate
