This research presents a dual-broadband antenna achieving omnidirectional and bidirectional radiation for 5G and Wi-Fi, suggesting robust performance.
This paper presents a compact dual‐broadband pattern diversity antenna designed for 5G and Wi‐Fi applications. The proposed design combines a pair of short and long monopole structures with a radiating patch to achieve omnidirectional radiation in the lower band (2.53–3.31 GHz) and bidirectional radiation in the upper band (5.49–6.06 GHz). By leveraging mode superposition, the antenna maintains stable gain across both frequency ranges, with measured realized gains of 2.29 and 2.95 dBi, respectively. The structure features wide impedance bandwidths of 26.7% and 9.9%, while maintaining a low‐profile form factor of 0.013λ L . Experimental results align well with simulations, confirming the antenna's effectiveness for multi‐system coverage. Due to its compact size and enhanced performance, this antenna is well suited for wireless communication systems.
