N2 - A dual-port dual-sense wideband circularly- polarised (CP) printed slot antenna is proposed. The compact coplanar waveguide (CPW)-fed antenna is proposed for ambient energy harvesting applications. Two identical CPW feeds excite ±45° fan-shaped stubs in the elliptical slot, providing a wide bandwidth. By separating the ground plane and slot by two narrow strips, an isolation better than 19.4 dB between the ports is achieved. The measured impedance bandwidth is 850 MHz (2.08 GHz to 2.93 GHz) and the 3dB axial-ratio bandwidth is 870 MHz (2.04 GHz to 2.91 GHz).
