Stacked circular microstrip patch antenna with increased bandwidth

In order to obtain larger bandwidth a stacked circular microstrip patch antenna has been investigated. A line transformer has been applied to achieve input impedance matching in a larger bandwidth. This configuration offers larger bandwidth but still maintains planar shape, low profile of the antenna and manufacturing simplicity. The stacked patch antenna showed very good gain. The co-polar and cross-polar radiation patterns were not significantly affected by the line transformer.
