A single layer broadband millimetre wave (mm-wave) array with circular polarisation is proposed for the fifth generation (5G) mm-wave communication applications. The antenna element is designed to integrate the matching circuit into a single layer. Hence no additional matching and feeding networks are required which makes the antenna element very easy to synthesise a massive array. The array has a 10 dB return loss bandwidth between 26 GHz and 32 GHz. The polar angle axial ratio is less than 3 within the beamwidth of -60 degree to 60 degree. The proposed antenna structure is simple, low cost and robust, which we envisage suitable for the massive multiple-input and multiple-output (MIMO) applications.
