AʻO ka antenna horn broadband he antenna kuhikuhi me nā hiʻohiʻona wideband. Loaʻa iā ia kahi alakaʻi nalu e hoʻonui mālie ana (ke ʻano o ka pū). ʻO ka hoʻololi mālie ʻana o ke ʻano kino e hoʻokō i ka hoʻohālikelike impedance, e mālama ana i nā hiʻohiʻona paʻa radiation ma kahi ākea ākea (e laʻa, mau octaves). Loaʻa iā ia nā pōmaikaʻi e like me ka loaʻa kiʻekiʻe, ke kukui haiki, a me ke kuhikuhi pololei. Nā noi nui: EMC ho'āʻo (radiated emission/immunity testing), radar system calibration (gain reference), millimeter wave communications (satellite/5G high-frequency verification), and electronic countermeasures (broadband signal detection).
ʻO ka antenna log-periodic he antenna frequency-invariant i loaʻa i kahi pūʻulu o nā mea oscillator e emi mālie ana i hoʻonohonoho ʻia i loko o kahi ʻano logarithmic periodic. Loaʻa iā ia ka hana broadband ma o ka geometric self-similarity. Paʻa mau kona ʻano hoʻolalelale i loko o ke alapine, me ka loaʻa haʻahaʻa a me nā ʻano hopena ahi. ʻO kāna mau noi mua, ʻo ia ka: EMC hoʻāʻo (30MHz-3GHz radiated emission scanning), ka nānā ʻana i ka hōʻailona (electronic reconnaissance and spectrum analysis), ka hoʻokipa kīwī (UHF/VHF full-band uhi), a me nā kahua kahua kamaʻilio (hoʻohana ʻana i nā hui lehulehu).
No ka ʻike hou aku e pili ana i nā antenna, e kipa:
