A Printed Antenna Design with Defected Ground Structure for Multiband Applications

Abstract

In this paper, the design and analysis of a printed antenna based on a defected ground structure for multiband applications is introduced. The proposed antenna consists of two rectangular slots like an inverted stair. Different five strip lengths are in the area of an inverted stair slot. Four strips are equal in width and horizontally located inside the main two rectangular slots. The fifth strip is the smallest one in the middle of the structure in the ground plane. The microstrip line exists only on the front side plane and parallels to the fifth strip. The antenna is printed on a hydrocarbon ceramic substrate with a dielectric constant of 3.55 and a size (40 × 45 × 1.524) mm3. The proposed antenna is designed by using an electromagnetic simulator based on the finite element method. To verify the suggested approach, the multiband antenna is fabricated and tested. The simulation and measurement results indicate that the antenna has good input-impedance bandwidths (S11 ≤ −10 dB) that extend in the range of 2 to 14 GHz. The six operating frequencies are (2.58, 6.03, 6.25, 7.89, 11.64, and 12.24) GHz. This antenna has good gains and high efficiencies at all resonance frequencies.
