Rectangular Slotted Microstrip Patch Antenna with Partially Loaded Metamaterial Ground Plane

چکیده
In this paper, a rectangular slotted microstrip patch antenna with partially loaded metamaterial multiple-split ring resonator (MSRR) ground plane is presented. In unloaded condition, the rectangular slotted patch antenna resonates at 9.38 GHz. When the same antenna is loaded with MSRR in the ground plane, it resonates at lower resonant frequencies 4.60 GHz and 7.70 GHz respectively. The mutual coupling between the slots leading to mismatch at lower resonant frequencies is analyzed in this paper. The MSRR loading reduces the mutual coupling in order to obtain better matching at these resonant frequencies. The simulated result of MSRR is validated using the principles of equivalent circuit theory. The size of antenna at lower resonant frequency is 0.306 λ × 0.153 λ.
