| 摘 要： | 由于软对数周期天线所使用的软索具有弯曲悬垂变形的特点,对于大尺寸天线可能导致集合线严重弯曲变形。通过对拉杆变形的理论分析,有效地利用其特点,使天线集合线呈水平状态,振子呈垂直状态,实现天线的保形,从而满足电气要求。在材料的选择方面,特制电缆、特制软线和迪尼玛绳都非常适合工程的使用。

| Abstract: | The Soft Log-Periodic Antenna has the characteristic of pendency,which will cause serious deformation of the parallel transmission lines,especially for the large size antenna.According to the theory of cord deformation,if a nonmetallic compensative cord is added between the end of the dipoles and the cord,the parallel transmission lines will be level and the request of the formwill be reach.In the aspect of material,Customizable cable,Customizable soft wire and Dyneema are all suitable for project application. |
