ʻO ka log-spiral antenna he antenna angular maʻamau nona nā palena lima metala i wehewehe ʻia e nā pihi spiral logarithmic. ʻOiai e like ka nānā ʻana me ka spiral Archimedean, ʻo kona ʻano makemakika kūʻokoʻa e lilo ia i "antenna kūʻokoʻa-frequency."

Ke hilinaʻi nei kāna hana i kona ʻano hoʻohui ponoʻī (ʻano like ke ʻano metala a me ka ea) a me kona ʻano angular maʻemaʻe. ʻO ka ʻāpana hana o ka antenna ma kahi alapine kikoʻī he ʻāpana ʻano apo me ke anapuni o kahi lōʻihi o hoʻokahi nalu. Ke hoʻololi nei ka alapine hana, neʻe mālie kēia ʻāpana hana ma nā lima spiral, akā mau kona ʻano a me nā hiʻohiʻona uila, e hiki ai i ka bandwidth ākea loa.

ʻO nā pōmaikaʻi koʻikoʻi o kēia antenna ʻo kāna hana ultra-wideband (nā bandwidth o 10: 1 a i ʻole ka mea maʻamau) a me kona hiki ke hoʻomālamalama i nā nalu circularly polarized. ʻO kāna mau drawbacks he haʻahaʻa haʻahaʻa loa ia a me ka pono o kahi pūnaewele hānai paʻakikī paʻakikī. Hoʻohana nui ʻia ia i nā noi e koi ana i ka hana wideband, e like me Electronic Countermeasures (ECM), kamaʻilio broadband, a me nā ʻōnaehana nānā spectrum.
