broad band antenna meaning in English

宽频带天线

The comparison between the results of calculation and measurement shows that the two results are in good agreement for the broad band antenna in the l band and the waveguide - coax converter of bj48 type used as antenna in the c band , with a difference of less than 0 . 7db , and that the two results also agrees well in the x band for the waveguide - coax converter of bj100 type used as antenna , with an error close to 1db only at few points in the given frequency range
比对结果表明: l波段(加脊天线) 、 c波段( bj48型波导同轴转换作为接收喇叭)的模拟结果与实测结果符合得较好,误差小于0 . 7db ;在带内, x波段( bj100型波导同轴转换作为接收喇叭)的模拟结果与实测结果比较一致,只在个别频率点处误差近1db 。
