The main objective of this paper to implement 2 × 2 multiple-input multiple-output (MIMO) system and also to design four mutually orthogonal MIMO patch antennas with a single substrate, which are fed by four microstrip lines using the same resonant frequency of 2.45 GHz which is also applicable to the WLAN. In this paper, the basic patch antenna using coaxial probe feed and basic patch antenna using a microstrip line feed, which is fed by a microstrip line, were designed by using resonant frequencies of 2.45 GHz which is used for applications like industrial, scientific, and medical (ISM) band. Basically, this concept is a type of technology for wireless networks that allows access points or wireless routers to have multiple antenna. Multiple-inputs and multiple-outputs (MIMO) referring to the fact that it is a wireless technology, which is used to transfer more data at the same time between transmitter and receiver to increase data rate and minimize errors.
