【摘要】：設(shè)計(jì)一種可用于W-CDMA,TD-SCDMA等2G/3G/4G-LTE通信標(biāo)準(zhǔn)網(wǎng)絡(luò)的寬頻帶雙極化印刷振子基站天線單元.天線由兩個(gè)雙層貼片結(jié)構(gòu)十字交叉組成,在饋電巴倫底部采取梯形彎曲結(jié)構(gòu),提高了雙端口的隔離度,便于組裝;在貼片雙臂上端附加短路T形貼片結(jié)構(gòu),展寬了帶寬.實(shí)測結(jié)果表明:天線兩端口電壓駐波比≤1.5的帶寬均達(dá)到66.7%(1.65~3.30GHz),帶寬內(nèi)隔離度大于25dB,帶內(nèi)增益為4.1~8.3dBi.
[Abstract]:A broadband dual-polarization printed dipole base station antenna unit is designed for W-CDMA-TD-SCDMA and other 2G/3G/4G-LTE communication standard networks. The antenna is composed of two double layer patch structure cross, adopts trapezoidal bending structure at the bottom of feed Barron, improves the isolation degree of double ports, and adds short circuit T-shaped patch structure to the upper end of the patch arms, which broadens the bandwidth. The measured results show that the bandwidth of the antenna with VSWR 鈮，
