Abstract :
A conventional circular patch microstrip antenna (CPMA) is proposed on LiTi ferrite substrate in X-band (8-12 GHz) region. In this paper, we precise the preparation of a polycrystalline LiTi ferrite of 2200 Gauss 4 piMs and characterize their electric and magnetic properties as a substrate for CPMA. The comparison of radiation patterns and other parameters between normal dielectric substrate (Quartz) and substituted polycrystalline ferrite substrate (LiTi ferrite) CPMA shows the effective use of Li ferrites in antenna applications.
