Abstract: Smartphones are becoming extremely popular due to increasing demand for higher data traffic of mobile network. This drastic increase can be related to the population explosion. It has caused rapid development in telecommunication sector to improve performances of the radio signal transmission. In Bhutan, fifth generation (5G) communication was launched in 2021 but it has not been deployed in all region of the country. The ongoing pandemic has made us realize the impact of better connectivity through technology. There are still some challenges of 4G like spectrum crisis and high energy consumption. 5G Communication can provide high-speed data transmission with methods of millimeter-wave (mm-Wave) communication, miniaturization and multi-cell array antennas but antenna design is a challenge. Integrating multiple-input multiple-output (MIMO) technology into smartphone antenna can effectively increase the performance of spectrum efficiency and channel capacity. A 4x4 Dual band mm-Wave slotted patch array antenna for the 5G communication is proposed in this paper and the beam-forming will be performed. The proposed antenna is operating at LTE bands 30-40 GHz. The antenna can be used in mobile phones as well as in Base stations. The bandwidth, gain, directivity, reflection coefficient and VSWR will be studied for the antenna to meet the future 5G capabilities.
