  • Abstract The proposed dual-band circularly polarized antenna is featured to have a ringpatch and a square slot-ring etched on two opposite sides of an FR4 substrate. The antenna is aperturecoupled by a cross-slot through a microstrip line. Optionally, an air-layer can also be added to boost the gain of the antenna.
    The measured return-loss bandwidth of the antenna is 1.2% (1.23GHz~1.245GHz) and 24% (1.495 GHz~1.9 GHz). The 3dB axial-ratio bandwidth is 0.2% (1.241 GHz~1.243 GHz) and 5% (1.557 GHz~1.637 GHz).
    The peak gain of the antenna is 1.72dBic at 1.241 GHz and 7.04dBic at 1.575 GHz.
