Abstract

A dual-polarised monopole-slot co-located MIMO antenna is proposed for 2.4 GHz wireless local area network (WLAN) applications. The antenna consists of a monopole with its ground folded and a compact coplanar waveguide feed, providing the vertical and horizontal polarisations. The antenna is designed for a volume-limiting MIMO system due to its compact dimensions of 50 16 16 mm³ (0.4λ₀×0.128×₀×0.128×₀) and high isolation better than -24 dB. The performance of the proposed antenna has also been measured, including the S-parameters, the radiation patterns and the gain, which agree well with the simulation results.
