I need a wideband circularly polarised spiral printed antenna. It should be cavity backed for one sided radiation, or any other technic can be applied.

BW: 2.3-7.5 GHz, Low profile, high gain as much as possible, high front/back radiation ratio. Coaxial SMA feed. So may need to have balanced-unbalanced balun. If possible two ports 1. for RHCP other is LHCP.

It should be designe in CST,

Pls contacr for further details.
