摘要
摘要提出了一种采用LTCC衬底的提取极单元(EPU)双极化滤波天线。EPU实现了带通滤波器的高裙边特性，传输零点位于通带附近，无交叉耦合。在5G band -n257 (26.5-29.5 GHz)的28ghz频段设计制作了带EPU的滤波天线。测量到的s11在n257频段小于-10.6 dB，双极化两个端口之间的隔离度大于20.0 dB。在28.8 GHz频段测得天线峰值增益为4.0 dBi，在n257频段测得增益大于2.5 dBi。测得的天线增益频率特性显示出带外高裙边特性，与电磁仿真结果吻合较好。
A 28 GHz Band Compact LTCC Filtering Antenna with Extracted-Pole Unit for Dual Polarization
SUMMARY This paper proposes a dual-polarized filtering antenna with extracted-pole unit (EPU) using LTCC substrate. The EPU realizes the high skirt characteristic of the bandpass filter with transmission zeros (TZs) located near the passband without cross coupling. The filtering antenna with EPU is designed and fabricated in 28 GHz band for 5G Band-n257 (26.5-29.5 GHz). The measured S 11 is less than -10.6 dB in Band-n257, and the isolation between two ports for dual polarization is greater than 20.0 dB. The measured peak antenna gain is 4.0 dBi at 28.8 GHz and the gain is larger than 2.5 dBi in Band-n257. The frequency characteristics of the measured antenna gain shows the high skirt characteristic out of band, which are in good agreement with electromagnetic (EM)-simulated results.
