Mobile technology is a fast developing technology which gives a huge impact on social life nowadays. This non wired technology urges a study need for antenna development where antenna can be said as the core device for this technology. Researches on antenna are rapidly developing in the current research trend resulting in many antenna designs in modern wireless technology because it allows single antenna to be employed in many systems. 5 Generation is the next generation for mobile technology, which have many advantages such as better data rate, better reliability, network scalability and flexibility, amazingly fast, super real time, better efficiency and great service in a crowded area. This research work is focusing on the array antenna that operates at 28 GHz band. The configuration of antenna consists of single patch which is replicated to construct an array in horizontal direction with coaxial feeder from behind. This gives better distribution for the current and better radiation pattern. The length of single patch control the operating frequency. The width of short side and long side controls the gain and the shape of the radiation pattern. This antenna has a high gain, which can reach 17dB and its impedance bandwidth is more than 1 GHz. The radiation efficiency is measured is more than 92% with a return loss of not less than -20dB. Also this project suggested formulas for calculating the gain versus the number of arrays and how the gain can be increased with respect of thickness. Computer simulation Technology (CST) was been used as the simulator and the results was measured through Network analyzer.
