A lens based on spatially combining the outputs from a printed curl antenna operating at 2.49 GHz and capable of converting either LH or RH CP incident energy into RH or LH CP is demonstrated. The lens, which is of small area has low profile and uses a dual sided 3x3 array of curl antenna elements. The structure has 30.3 dB gain and high isolation between input and output due to its polarisation conversion properties.
