Abstract :
An improved wideband circularly polarized microstrip antenna is here proposed and analyzed. The radiating structure consists of a simple patch with a basic shape ldquoChalipardquo, two rotated broken and crossed ldquoSrdquo, which has been iterated by a fractal pattern achieving a multiband or even wideband, structure. The basic shape represents a clockwise rotation that results in the same rotation of current direction and therefore the electromagnetic fields. This special characteristic of the antenna makes a significantly wideband circular polarization and compensates the bandwidth restrictions of microstrip antennas.
