Abstract
A patch antenna with wider bandwidth, better axial ratio over the angle and controlled radiation patterns is provided. A central fixed patch antenna is surrounded with reactively or resistively loaded peripheral monopoles as surface-wave excited parasitic radiators. The surrounding monopoles may be printed on the same substrate as the patch, and may take a spiral (pin-wheel) shape.
