摘要
文中提出了一款基于机载应用的变形套筒式天线,该天线具有全向辐射特性及高增益、小型化特点,天线剖面低,其外形具有良好的气动性,满足机载应用对天线高增益和低气动阻力的需要。天线高度小于0.17倍为最长工作波长;工作频段内电压驻波比小于等于3;110～250 MHz天线增益大于等于-3 dBi,250～550 MHz天线增益大于等于0 dBi;工作频段内不圆度小于等于±1.5 dB。
In this paper,a deformed sleeve antenna is proposed for airborne application.It does well in omnidirectional radiation,high gain and miniaturization.This antenna has low profile and good aerodynamic performance,which can meet the requirements of airborne antenna.Its height less than 0.17λ_l,whereλ_l is the maximum working wavelength;VSWR less than 3 within working frequency band;Gain≥-3 dBi from 110 MHz to 250 MHz and≥0 dBi from 250 MHz to 550 MHz;Out of roundness less than 3 within working frequency band.
