摘要：
This paper presents a new Defected Ground Structure (DGS) to enhance the isolation between two closely spaced circular patches for wireless applications. The antennas are placed on a Roger substrate with a relative permittivity of 3 and thickness of 1.52 mm. Four arcs are slotted on the ground underneath the substrate to eliminated the mutual current interacting between the elements. An enhancement of 26 dB has been achieved with a separation of 0.05 lambda(0) at 4.8 GHz. The total realized gain at the resonance frequency after the isolation is 5.2 dB. The array is suitable for applications where compact circular patches array is suitable.
