摘　　要：提出了一种新型"V"型天线,并运用实频匹配技术使该天线在25MHz-85MHz获得了优秀的天线性能。该天线在频段范围内VSWR<3,增益主要分布在0-2dB之间,最小增益不低于-6dB,天线效率大于75%,可广泛运用于军事、遥感、环境监测等领域。The UHF antenna with high performance is a topic that people are constantly researching. This paper puts forward a new type of “V” Antenna ,and using Real Frequency Method to make the antenna obtained a excellent design between 25MHz to 85MHz. The VSWR of the antenna is below 3 ,gain is be-tween 0dB to 2dB in the main frequency range,and the minimum gain is no less than -6dB. Then,the efficiency of the antenna is more than 75%. So,it can be widely used in military,remote sensing and envi-ronmental monitoring.
