The new extended Wi-Fi band of 5.4 GHz band is less congested compared to the traditional 2.4 GHz band. The ability to handle large traffic of this 5.4 GHz band captured the interest of most researchers and hence there is a need to developed efficient antennas at 5.4 GHz frequency. This manuscript presents a novel compact V-cut patch antenna for the 5.4 GHz Wi-Fi application. The proposed design is a (2  $$\times$$  1) MIMO antenna with a partial ground structure. The patch structure and partial ground were optimized using simulation software. The simulated structure is optimized using an optimizer. The optimized structure is fabricated on the FR-4 substrate and tested for performance metrics. The proposed MIMO antenna was found out to be a wideband antenna with an overall bandwidth of 1500 MHz. The measured gain was 3.86 and the Return loss (S11) value was $$-23$$  dB which closely resembles a simulated value of −27 dB. The proposed MIMO antenna is compact size 32 mm  $$\times$$  56 mm and can be used with existing Wi-Fi routers to increase the capacity of the channel and throughput of the system.
