Abstract
In this work, a stacked ring spiral antenna has been proposed, the metallic ring is stacked behind the spiral antenna with the help of FR-4 substrate (dielectric constant=4.3 and loss tangent 0.025), after the ring attachment lowest frequency of spiral antenna is down shifted by 590 MHz. The size miniaturization is 42.5% with improved axial ratio.
