Miniaturized planar dipole antenna with enhanced gain for WLAN applications using AMC surface

Year: 2025

Type: article

Abstract: This paper proposes a dipole antenna with broadband characteristics for WLAN application. To achieve a wide operational bandwidth, the defected ground structure (DGS) technique is integrated on the ground. As a result, the percentage of bandwidth is risen from 15% to 28% for simulation. In addition, the miniaturization technique is implemented by using zigzag lines and angled at 90o while Artificial Magnetic Conductor (AMC) surface is utilized to enhance gain for the antenna. The final design, including two elements (array of 1 × 2), witnesses an overall volume of 0.93λ0 × λ0 × 0.12λ0, in which λ0 is the free-space wavelength at the lowest operating frequency of 4.64 GHz. At −10 dB, the bandwidth impedance is 28% for simulation (4.638–6.172 GHz) while the peak gain accomplishes 10.3 dBi.
