Design of Compact UWB Microstrip Antenna Using DoubleLayer 2D Periodic Structure
Journal Title: IOSR Journal of Electronics and Communication Engineering(IOSR-JECE) - Year 2018, Vol 13, Issue 4
Abstract
This paper describes a compact ultra-wideband (UWB) antenna designed on a low-cost FR4 substrate using planar-patterned metamaterial concepts. The proposed antenna incorporates two components of metamaterial structure made by etching a T-shaped slots on the main radiating patch and W-shaped slots on the ground plane. The total size of the proposed antenna is 27.6×31.8 mm2 , with a substrate thickness of 1.6 mm, relative permittivity of 4.5, and loss tangent of 0.02. Applying the -10 dB criterion, the 50 Ω impedance bandwidth is from 3.3 GHz to more than 17 GHz, with a standing wave ratio (SWR) of less than 2 over the whole band. The average gain over the entire bandwidth is 5.8 dB, with a peak value of 6.9 dB at 12.2 GHz. The proposed antenna was designed and simulated using the finite integration technique (FIT)-based CST microwave studio. Good agreement between measurement and simulated results was obtained. Thus, the proposed antenna could be applied to UWB wireless communications in the future.
