Dual-band CP radiation can also be achieved by using a spiral slot [13], or a CPW-fed annular slot with two perturbation strips [14]. In [15], a square microstrip patch antenna embedded with four slots and a crossed slot can generate dual-band CP radiation. But all these designs in [13{15] have a limited
2012-8-3 · A dual-band CP antenna using single layer patch has been reported in [4], [5]. In [4], an antenna consists of a circular patch and a narrow annular ring is designed. This antenna achieves its CP operation by an equal cross slot embedded on the circular patch. The design of antenna in [5] consists of a small circular patch surrounded by two
