Abstract :
A feed structure composed of multi-eccentric ring slots was proposed to feed DRA elements for multi-frequency operation. Simulated results show that the structure is valid. The coupled slots, excited by a coaxial cable in this work, can also be excited by other form feed structures, such as a microstrip line, or a coplanar waveguide (CPW).
