【摘要】：設(shè)計了一款應(yīng)用于4G手機終端新型六頻段天線。采用倒L型、U型、S型輻射枝節(jié)獲得多頻特性;短路加載技術(shù)讓低于諧振頻率的點達(dá)到阻抗匹配;耦合饋電方式代替?zhèn)鹘y(tǒng)的直接饋電以減小阻抗波動,獲得較寬頻帶。該天線尺寸僅占70 mm×16 mm×1.5 mm,能夠覆蓋手機通信的6個頻段:LTE700,CDMA/GSM850,GSM900,DCS1800,PCS1900,WCDMA/UMTS2100。測試結(jié)果表明,在工作頻段內(nèi),散射參數(shù)S11≤-6d B,電壓駐波比VSWR≤3,均達(dá)到工程要求的指標(biāo),驗證了設(shè)計的可行性。
[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，
