Study of Linear Array of Microstrip Hexagonal Patch Antenna Printed on LiTi Ferrite under External Magnetic Biasing

摘要

Characterization of a tunable & switchable microstrip hexagonal patch linear array antenna printed on synthesized LiTi ferrite substrate with a normal magnetic bias field is presented. The DC magnetic biasing offers number of novel magnetic and electrical characteristics including tunable and polarized radiations from the microstrip antenna. In such a case of substituted polycrystalline ferrite antenna with DC biasing, most of the power will be converted into mechanical waves and little radiates into air. Under such condition the antenna become switch off, in the sense of effectively absence as radiator. Some electric and magnetic properties of substrate is also described with precise SSRT method of substrate material preparation.
