新型平面交叉耦合偶极子天线

内容简介：本文提出一种新型平面交叉偶极子天线.该天线以原平面单极子天线为原型,通过采用交叉馈电和缝隙耦合技术将单极子拓展为异面偶极子,实测和仿真数据显示在频段0.8GHz～1.0GHz/1.7GHz～2.5GHz的驻波比均在2.0以下,低频段增益为2.62dB,高频段增益为4.21dB.该天线结构尺寸紧凑,易隐藏且安装方便,偶极子的结构使得可以在天线中心馈电,便于实际应用.

Abstract：A new type of planar cross-coupled dipole antenna is demonstrated in this paper. The antenna structure originates from planar monopole antenna by adoption of cross-coupled feeding. Slot method is also used for band expansion and matching. The measured and simulated data show that the VSWR in the band 0.8 GHz-1. 0 GHz and 1.7 GHz-2.5 GHz were below 2.0, and the low frequency gain was 2.62 dB, the high frequency gain was 4.21 dB. The antenna compact size, central feeding position and was convenience forhiding and fixing make it feasible for practical application in indoor coverage system of GSM,CDMA,DCS,PHS,3G and WLAN.
