A planar periodic leaky‐wave antenna with filtering capability, circular polarisation, and wideband performance is presented. Seamless beam scanning from backward to forward is provided by self‐matching the unit cell of the antenna over a large frequency band from 22 to 28 GHz. A wide scanning range of 84° is achieved by using a relatively low‐permittivity dielectric material. Filtering capability is embedded in the antenna structure which contributes to the minimisation of the overall circuit size which is aimed in recent millimetre‐wave antenna in package systems. The proposed antenna has a circular polarisation with an axial ratio of <2 dB at broadside which makes it a good candidate for peer‐to‐peer and peer‐to‐multipeer communication systems.
