A new compact single layer ultra-wideband patch antenna is proposed. The antenna operates from 3.05 GHz to 10.9 GHz in the ultra-wide bandwidth range, which is more than the standard, set by FCC. The planar antenna is printed on FR-4 substrate material with a relative permittivity of 4.3 los tangent of 0.025. The structure is simple in design, small in size with total dimensions of 24 mm x 24 mm x 0.9 mm, and easy to fabricate. The measurements of the fabricated design compares well with simulation results. The overall characteristics of the planar antenna show that the design is well suitable for UWB applications. The presented compact antenna demonstrates higher performance compared with similar size recently published designs.
