Annular ring slot antenna designs with cp radiation

Single-Feed Circularly Polarized Annular Slot Antenna for Dual-Broadband Operation bended microstrip line and a cavity back. 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 antenna | Techn.
