CD-RAY Posted September 13, 2012 Author Report Posted September 13, 2012 (edited) ,,, see that written above ...!!!! Antenna without dielectric lens, can be placed in the focus of a parabola.But in this case, lowers gain antenna amounting to approx. 10 dBi...!!! Edited September 13, 2012 by CD-RAY Quote

verde_888 Posted September 14, 2012 Report Posted September 14, 2012 La asa ceva te-ai gindit cind ai postat?http://jpier.org/PIER/pier103/04.10022404.pdfSau la asta?IEEE Xplore - Performance analysis of a cylindric dielectric lens antenna for 77 GHz automotive radarAi postat un desen cu cote fara sa dai date mai multe.
