摘　　要：提出了一种小型化对数周期天线,采用集成LC匹配电路的V型振子进行加载,可在0.11λ1×0.16λ1×0.087λ1(长×宽×厚,λ1为低频截止频率对应波长)尺寸内,实现30MHz~1000MHz的工作带宽。该天线在30MHz~100MHz频段内电压驻波比实测优于3.2,在100MHz~1000MHz频段内电压驻波比实测优于2;在30MHz~50MHz频段增益实测优于-8dBi,在50MHz~150MHz频段增益实测优于-5dBi,在.150MHz~1000MHz频段增益实测优于5dBi。此外,天线的V型振子和各对称振子的结构采用可拆卸设计,易于包装携带。In this paper,a log periodic antenna is integrated with a LC matching circuit to expand its work band toward low frequency band.The traditional feed part was instead of the designed LC matching circuit,what loaded a V shape for easy carrying.The size of this proposed antenna is 0.11λ1×0.16λ1×0.087λ1(lengthx width×thickness),whereλ1 is the wave length at low cut-off frequency.Its work band is 30MHz~1500MHz VSWR is lower than 3.2 in the frequency range of 30MHz~100MHz,which is lower than 2 during 100MHz~1000MHz.Gain is higher than~8dBi range from 30MHzto 50MHz,which is higher than~5dBi during 50MHz~150MHz.In the frequency range of 150MHz~1000MHz,gain is higher than 5dBi.The proposed antenna has a compact structure,which can be easy realized.
