Abstract

A novel multi-mode narrow-frame antenna is presented for 4G/5G metal-rimmed mobile phones in this paper. The proposed antenna is constituted by a monopole antenna and a coupling strip, which is printed on FR4 substrate with thickness of 0.8 mm. The overall area occupied by the antenna is only 60 × 10.4 mm2, which can be used as a promising narrow-frame antenna. The simulated results shows that the return loss of the antenna can provide four operating bandwidths of 822– 961 (band 1), 1697–3075 (band 2), 3280–3835 (band 3) and 4475–5050 MHz (band 4), which respectively cover 824–960, 1710–2690, 3300–3600 and 4800–5000 MHz in 4G/5G communication systems. In order to verify the accuracy of theoretical analysis and simulated results, the proposed antenna is fabricated and measured. The experimental results are basically consistent with the simulated results, suggesting that the presented antenna has attractive performance for mobile phones.
