This paper presents the low profile, planar, and small-size antenna design for WWAN, LTE, and 5G (5th generation wireless systems) for use in portable communication equipment. The antenna occupies only 65 × 13 × 0.4 mm3, and the antenna is combined with a 200 × 260 mm2 copper plate to simulated system ground plane. In the low band, a direct-fed right-side arm and a coupled-fed arm implemented can excite a 1/4 λ fundamental resonant mode at 0.85 and 0.76 GHz to cover 0.698–0.96 GHz and upper 3/4 λ and 5/4 λ resonant modes are controlled by L-shaped element at 2.34, 2.69, 3.4, and 4.0 GHz to cover 1.71–2.69 GHz and 3.2–4.2 GHz. The direct-fed left-side arm produced 1/4 λ to cover 5.15–5.85 GHz. In far-field measured, peak gain and efficiency in low, middle, and high bands are 0.43–5.67 dBi and 55–86%. Finally, experiments demonstrate that the present antenna exhibits a good performance for portable devices.
