| 1. | Then , lump loading is used to enhance the valid height of the antennas , as a result the input impedance of the monopole antenna undergoes gently variation with frequency , and consequently it is easy to match by wideband matching network 加载后,输入阻抗变化得到减缓,这是能够使用宽带匹配网络进行宽带匹配的前提,经过宽带匹配达到了天线小型化和宽带化的设计目的。 |
