Iyo log-spiral antenna ndeye classic angular antenna ine simbi ruoko miganhu inotsanangurwa ne logarithmic spiral curves. Kunyange zvichitaridzika zvakafanana neArchimedean spiral, chimiro chayo chakasiyana chemasvomhu chinoita kuti ive yechokwadi "frequency-independent antenna."

Kushanda kwayo kunoenderana nekuzvimiririra kwayo (simbi nemhepo mapeji akafanana muchimiro) uye ayo chaiwo angular hunhu. Nzvimbo yeantenna inoshanda pane imwe frequency inzvimbo yakaita serin'i ine denderedzwa inosvika imwechete wavelength. Sezvo mafambisirwo ekushanda achichinja, iyi dunhu rinoshanda rinofamba zvakanaka richitevedza spiral maoko, asi chimiro chayo nemagetsi maitiro anoramba akamira, achigonesa yakafara bandwidth.

Mabhenefiti akakosha eiyi antenna kuita kwayo kwekupedzisira-kufara kwebhendi (bandwidths e10: 1 kana kupfuura zvakajairika) uye kugona kwayo kupenya mafungu akatenderedzwa. Zvipingamupinyi zvaro zvikuru ndezvishoma kuwana uye kudiwa kweiyo yakaoma yakaenzana feed network. Inoshandiswa zvakanyanya mumashandisirwo anoda wideband mashandiro, senge Electronic Countermeasures (ECM), Broadband kutaurirana, uye spectrum yekutarisa masisitimu.
