Abstract: Antennas with a high gain, good radiation efficiency, and an omnidirectional radiation pattern over a wide bandwidth will be able to solve some of the issues of existing communication networks. In this work a comparative analysis of different types of 5G antenna along with their performance improvements techniques are discussed. In this study we also proposed a simple planar printed antenna which is also offered high gain and desired radiation efficiencies. The proposed work is different in that, despite being a planar printed antenna, the antenna achieves a wider bandwidth of 4.5 GHz, peak gain of 11.6 dB, radiation efficiency of 92%, VSWR of 1.2, and SAR of 1.42 W/Kg for 1 g of tissue by utilising a U-shape slot over the radiating patch structure, and also useful for 5G-IoT-based infrastructure developments as a replacement for multi-layer antennas.
