Abstract

DGS is a method by defecting the ground plane of the microstrip antenna. By using this method, the antenna become more compact than the dimension of the conventional size. This paper present comparison of defected ground structure shapes effect to the size of the antenna. Antenna DGS of dumbbell shape, complementary split ring resonator and U shape are investigated and analyzed. From the result, it shows that by using dumbbell shape it achieve size reduction 12.965% from its conventional size, for the complementary split ring resonator the antenna size decreasing above of 47.738% from conventional size meanwhile for U shape provide up to 37.735% size reduction of conventional antenna.
