This letter investigates a fluid antenna system (FAS) where multiple portscan be activated for signal combining for enhanced receiver performance. Given$M$ ports at the FAS, the best $K$ ports out of the $M$ available ports areselected before maximum ratio combining (MRC) is used to combine the receivedsignals from the selected ports. The aim of this letter is to study theachievable performance of FAS when more than one ports can be activated. We doso by analyzing the outage probability of this setup in Rayleigh fadingchannels through the utilization of Gauss-Chebyshev integration, lower boundestimation, and high signal-to-noise ratio (SNR) asymptotic approximations. Ouranalytical results demonstrate that FAS can harness rich spatial diversity,which is confirmed by computer simulations.
