漏泄同轴电缆(LCX)是一种馈线,起着发射电磁波的天线作用,并且在电缆长度方向上的场波动较小.由于调频无线电广播(80MHz)到便携式数字电话(1900MHz)使用的频段宽度不断提高,所以必须扩展该频段.采用下面两个改进措施,新颖的LCX在80MHz~2600MHz频段(比普通LCX覆盖的最宽频段80MHz~900MHz要宽得多)显示出了良好的辐射特性.第一,通过槽长的最佳化来严格控制其辐射方向,从而使多模辐射段的场波动范围减至最小.第二,开设与辐射无关的仿真槽,从而在每半个槽组节距中减小反射引起的阻抗失配.
Leaky Coaxial Cable (LCX) is a feeder that acts as an antenna that emits electromagnetic waves and has less field fluctuations in the length of the cable Because of the wide band used by FM radio (80 MHz) to portable digital phones (1900 MHz) , The frequency band has to be expanded, and the novel LCX shows good radiation characteristics in the 80MHz ~ 2600MHz band (wider than the widest band 80MHz ~ 900MHz covered by a common LCX) with the following two improvements: First, through the optimization of the slot length to strictly control the radiation direction, so that the multi-mode radiation section of the field fluctuation range to a minimum.Second, the establishment of radiation-independent simulation of slot, which in each half of the slot group pitch Reduce the impedance caused by the impedance mismatch.
