Design of Wideband Printed Monopole Antenna Using WIPL-D

For the purpose of wideband operations, a printed monopole antenna fed by a microstrip line is investigated. A single element is studied before using it to form a linear array or two-dimensional antenna array system. The antenna element has a single T-shaped radiator fed by a microstrip line. This design is found to be useful for the entire C-band frequency range centered at 6 GHz. The computed return loss is presented that shows a bandwidth of 77%, with a 50 Ω input impedance. The radiation pattern is as presented for the proposed antenna at 6 GHz exhibits very low cross polarization. The effect of varying the monopole dimensions on the antenna performance has also been studied. The single element design was analyzed using the WIPL-D software package, which is based on method of moment solution.
