摘要

A novel type of turtle-shaped dielectric resonator antenna is proposed for use in ultrawide-band applications. Nine layers of different shapes of slabs are integrated and excited through a conformal strip. This staired-pyramid-type structure provides a large surface area for higher radiation efficiency. The integrated antenna is built on a defected ground structure to enhance the bandwidth of the antenna. The simulations and measured results for a fabricated prototype antenna for use in ultra-wideband applications are found to be in good agreement. The proposed antenna operates from 3.0 to 10.9 GHz (bandwidth 7.9 GHz), providing an impedance bandwidth of 114%. The ultrawide bandwidth is achieved by proper mixing of lower and higher modes generated through the slabs.
