【摘要】：设计了一款应用于4G手机终端新型六频段天线。采用倒L型、U型、S型辐射枝节获得多频特性;短路加载技术让低于谐振频率的点达到阻抗匹配;耦合馈电方式代替传统的直接馈电以减小阻抗波动,获得较宽频带。该天线尺寸仅占70 mm×16 mm×1.5 mm,能够覆盖手机通信的6个频段:LTE700,CDMA/GSM850,GSM900,DCS1800,PCS1900,WCDMA/UMTS2100。测试结果表明,在工作频段内,散射参数S11≤-6d B,电压驻波比VSWR≤3,均达到工程要求的指标,验证了设计的可行性。
[Abstract]:A new six-band antenna used in 4G mobile phone terminal is designed. The multi-frequency characteristic is obtained by using the inverted L type U type and S type radiation section, and the short circuit loading technology makes the points below the resonant frequency reach impedance matching. The coupling feed method replaces the traditional direct feed to reduce the impedance fluctuation and obtain a wide band. The antenna size is only 70 mm 脳 16 mm 脳 1.5 mm, and can cover 6 frequency bands: LTE700 / GSM850 / GSM900 DCS1800 / PCS1900 WCDMA-UMTS2100. The test results show that, in the working frequency band, the size of the antenna is only 70 mm 脳 16 mm 脳 1.5 mm. The scattering parameters S11 鈮，
