A Modified Super-Wideband Planar Elliptical Monopole Antenna

In this paper, a modified planar elliptical monopole antenna design has been presented for super-wideband applications. The proposed antenna design is composed of an elliptical patch radiator, a tapered microstrip feed line, and a trapezoid ground plane. It has been demonstrated that the ratio bandwidth of 28.57: 1 has been achieved in the frequency range of 0.7-20 GHz by utilizing a tapered microstrip feed line. Measurements of the proposed antenna has also been done to validate the simulation results and a good agreement has been observed between both the results. Furthermore, the proposed planar antenna offers acceptable gain with good radiation characteristics for the entire bandwidth.
