Abstract

An UWB(ultra-wideband) antenna based on inverted F patch structure with coupled feeding for the next generation 5G smartphone are presented. The antenna fed by coupling is composed of a novel inverted F patch and a meander feedline. Three resonant modes are excited to obtain the characteristic of UWB. The simulated -6dB impedance bandwidth of the antenna is 60.8% (3.27-6.13GHz), which can cover 5G communication band (n77: 3.3-4.2GHz, n78: 3.3-3.8GHz and n79: 4.4-5.0GHz) and WiFi band (5.1-5.9GHz). The antenna exhibits good radiation efficiency performances with 76.0%-91.7% over the whole operation band.

5G智能手机的超宽带耦合馈电倒F天线

提出了一种用于下一代5G智能手机的基于倒F贴片结构耦合馈电的超宽带(UWB)天线。耦合馈电天线由一种新颖的倒F贴片和弯曲馈线组成。通过激发三种谐振模式来获得超宽带的特性。天线模拟-6dB阻抗带宽为60.8% (3.27-6.13GHz)，可覆盖5G通信频段(n77: 3.3-4.2GHz、n78: 3.3-3.8GHz和n79: 4.4-5.0GHz)和WiFi频段(5.1-5.9GHz)。该天线在整个工作波段的辐射效率为76.0% ~ 91.7%。
