The antenna is coupled by a microstrip line through a slot-ring configuration. The radiator of the antenna has a slit loaded square-patch and a slit-loaded square-ring. The slit-width and the slit-length are tuned to generate circularly polarized waves, which can be achieved at two bands.
In summary, the antenna has 10dB return-loss bandwidth 13.2% (1.41GHz - 1.61GHz) at the low-band and 12% (2.2GHz - 2.48GHz) at the high-band. The antenna has 3dB axial-ratio bandwidth at the low-band and the high-band 1.9% (1.57GHz - 1.59GHz) and 2.1% (2.425GHz - 2.475GHz). The antenna boresight gains at 1.575GHz and 2.45GHz are more than 5dBic.
