ʻAntenna Waveguide Slotted 22dBi Typ. Gain, 9-10GHz Frequency Range Edit RM-SWA910-22

ʻO kahi antenna waveguide slotted he antenna huakaʻi-nalu kiʻekiʻe e pili ana i kahi ʻano waveguide. ʻO kāna hoʻolālā kumu e pili ana i ka ʻoki ʻana i kahi moʻo o nā slots e like me kahi ʻano kikoʻī i loko o ka paia o kahi waveguide rectangular. Hoʻopilikia kēia mau slots i ke kahe o ke au ma ka paia o loko o ka waveguide, a laila e hoʻolaha ana i ka ikehu electromagnetic e hoʻolaha ana i loko o ke alakaʻi i kahi ākea manuahi.

ʻO kāna kumu hana penei: i ka hele ʻana o ka nalu electromagnetic ma ke alakaʻi nalu, hana kēlā me kēia lua ma ke ʻano he mea hoʻomālamalama. Ma ka hoʻomalu pono ʻana i ka mamao, ka ʻūlū ʻana, a i ʻole ka offset o kēia mau lua, hiki ke hoʻohui ʻia ka radiation mai nā mea āpau i ka pae ma kahi kuhikuhi kikoʻī, e hana ana i kahi kukuna penikala ʻoi a kuhikuhi kiʻekiʻe.

ʻO nā pono nui o kēia antenna ʻo ia kona ʻano paʻa, ka mana hoʻokele mana kiʻekiʻe, ka pohō haʻahaʻa, ka pono kiʻekiʻe, a me ka hiki ke hana i nā ʻano radiation maʻemaʻe loa. ʻO kona mau hemahema nui he bandwidth hana haiki a me ka pololei o ka hana ʻana. Hoʻohana nui ʻia ia i nā ʻōnaehana radar (ʻoi aku ka radar phased array), nā loulou relay microwave, a me ke alakaʻi missile.
