Abstract
A triple-band ± 45° dual-polarized dipole antenna is presented in this paper. The proposed antenna covers two n77 bands and one n79 band in 5G NR frequency spectrums with S11, S22 <− 15 dB return loss. The profile antenna exhibits the measured impedance bandwidths of 250 MHz, 150 MHz and 350 MHz from the operating bands 3.6–3.85 GHz, 4.05–4.2 GHz and 4.8–5.15 GHz respectively. Antenna is fabricated with four substrates; one radiator, one reflector and two feeding baluns. Antenna is designed and optimized with HFSS simulator and fabricated for experimental verification. Antenna gives a stable radiation pattern of 8.55 dBi high gain with 70° half power beam width (HPBW) that makes it a good candidate for wireless 5G sub-6 GHz and multiband base station applications. Finally, antenna is tested in a realistic application environment to show the utility of the proposed antenna for wireless sub-6 GHz IoT applications.

Summary
INTERNET of things (IoT) is expected to be adopted for most of the electronic communication applications in near future. The IoT technology associated with integrated antennas is expected to make our future communications a very sophisticated and simple. The concept of internet ofthings (IoT) is known as extension of internet It is a worldwide interconnected emerging network of different objects associated with sensors, input/output devices, actuators and communication systems. Antennas are playing a vital role in the wireless sensor technology that leads to an emerging future with the development of IoT techniques. A loop antenna is presented in [3] for an IoT application with the antenna placement at different places. The technological development in different cellular and wireless applications has generated a high speed data rate requirement that leads to a fifth generation (5G) communication system. A low cost, low profile triple band ±45° dual-polarized dipole antenna is proposed for wireless 5G applications.
