Design of 28/38ghz Dual-Band Vertically Stacked Dipole Antenna for Millimeter-Wave 5G Communication

The rapidly evolving landscape of wireless communication technologies has led to the emergence of the fifth-generation (5G) networks, aiming to provide high data rates, ultra-low latency, and massive device connectivity. The millimeter-wave (mmWave) frequency bands, particularly around 28GHz and 38GHz, offer vast bandwidths to accommodate these requirements. This paper gives the design, simulation, and analysis of dual-band vertically stacked dipole antenna operating at 28GHz and 38GHz for mmWave 5G communication. The antenna design presented is compact and effectively addresses the requirement for extensive bandwidth through its dual-band configuration. The antenna architecture features symmetrical radiators tuned for the 38 GHz band, strategically placed both above and below a multilayer substrate. Additionally, radiator optimized for the 28 GHz band is situated at the central plane, resulting in a dual-band antenna structure characterized by its modest lateral dimensions. The compact dimensions, enhanced radiation attributes, and dual-band functionality of the suggested antenna render it a highly promising contender for the forthcoming 5G communication systems of the next generation.
