Abstract Microstrip antennas have become a part and parcel of today’s wireless communication world because of their low profile, low cost and ease of fabrication in the circuit boards. But poor performances like narrow bandwidth, low power handling capability, low gain etc. confine their application in some cases. 5th generation (5G) wireless communication will suffer from path loss severely, as high frequency bands will be used. To manage this problem, high gain antenna is required. So, this research is mainly devoted to design a high gain 2 × 2 microstrip patch array antenna. The structure of the antenna is designed and simulated using CST Microwave Studio and operates at 28 GHz 5G band. Rogers RTDuroid 5880LZ is used as the substrate which has a relative permittivity of 1.96. The return loss, gain, bandwidth, VSWR and efficiency of the designed 2 × 2 array antenna is 87 dB, 14 dBi, 1.14 GHz, 1 and almost 93% respectively.

1 Introduction Wireless communication has attracted the attention of human being due to its cost efficiency, feasibility, mobility, flexibility and many other attractive features since the beginning of its invention. As the development of human civilization is impossible without the progress in communication systems, the research and development (R&D) in the field of communication system has been growing at a massive rate, specifically in the last three decades. Without employing antenna, wireless communication can’t take place. The early types of antennas used in cellphones were the dipole, monopole, whip or helix antenna which were employed externally and had bad effects on user’s head and offered low performance as well [1]. After the introduction of internal antenna system such as microstrip antenna, it * Mohammad Nabil [email protected] Muhammad Mostafa Amir Faisal [email protected] 1

experienced a colossal rate in its uses in the mobile phones due to its better performances in terms of manufacturing cost, size and fabrication with printed circuit boards. So, microstrip antennas had captured the attraction of telecommunication industry and researchers in this field as well. Consequently, this study is also closely related to microstrip antenna. In the meantime, the demands of increment in telecommunication network capability has been rising immensely. To support these needs, telecommunication industry has evolved into new generations of wireless communication standards in almost every decade. Current 4G wireless network can provide a highest data rate of 100 Mbps, while the prese
