A Novel Nonlinear LPDA Design for HF Direction Finding by Xiaofei Ren, Hu Li, Shuxi Gong

“…Here, we propose a design method which uses the continuous change of both the scale factor and the spacing factor so that the length of the dipoles and the space between dipoles vary nonlinearly. One advantage of our design is that the effective distance between the phase center position and the feed point of LPDA can be increased. …”
