A novel compact monopole antenna with integrated services for 4G/5G application has been proposed in this manuscript. The 4G services such as Long Term Evolution (LTE) and GSM 850/900 is provided by the primary antenna of size 45 × 15 mm. The 5G communication services are supported by the auxiliary antenna of size 19 × 15 mm. The monopole radiator with the combination of multi-branch stubs and meandered structures in the primary radiator introduces the resonance at the desired operating frequency. The impedance bandwidth of the primary antenna is 170 MHz (0.8–0.97 GHz) and 900 MHz (1.8–2.7 GHz) for LTE and GSM applications. The impedance bandwidth of the auxiliary antenna is 7 GHz (13–20 GHz) for 5G application bands. To achieve the desired operating bands, the length and width of the stubs are used as the tuning parameters. The large ground plane of size 200 × 150 mm is used as the mock-up system for the proposed antenna structure. To enhance the coverage of the handheld devices, the primary and auxiliary antenna is integrated in the mock-up system. The efficiency and gain of the antenna are in the range of 3–5 dBi and 70–96%. The simulated and measured results are correlated with each other. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.
