MIMO 2x2 2.45 GHz Antenna Array with Polarizing Channel Separation

The paper is about the developed compact antenna array with a frequency of 2.45 GHz implementing MIMO 2$\times$2 technology by polarizing channel separation. The authors have also developed a single antenna array radiator in the form of a printed resonant antenna, as well as a matching device that reduces its wave impedance and two antenna array feeding systems were developed. The development requires conducting a simulation of an antenna array of four radiators was performed. It is located in free space and access point housing. The simulation revealed the influence of the access point housing on the parameters of the antenna array radiation pattern. The developed antenna array has high directional properties, low VSWR, low cost, and high manufacturability due to the use of the printed circuit board manufacturing method. It allows it to be used for spatial selection of subscribers in places with a large concentration of Wi-Fi users in the range of 2.4 to 2.5 GHz.
