Broadband High Power Low Insertion Loss Dual Directional Loop Couplers

ʻO ke ʻano kikoʻī, ua haku ʻia ka mea hoʻohui ʻaoʻao ʻelua me kahi alakaʻi nalu pōʻai a me nā alakaʻi nalu i hui pū ʻia. Ma ka hoʻololi ʻana i ka ikaika hoʻohui ma waena o ka hui ʻana.
Waveguide a me ka loop waveguide, hiki ke hoʻokō ʻia ka hoʻoili kuhikuhi ʻana o ka ikehu ma waena o nā alakaʻi nalu like ʻole. ʻO ka mea nui o ka mea hoʻopili loop directional he poloka dielectric circular, i haku pinepine ʻia me ka tubular a i ʻole ka ʻāpana-like block, me kahi laina microstrip pōʻai i loko o ka poloka. Ke komo ka hōʻailona alapine kiʻekiʻe i ka poloka dielectric annular mai kekahi o nā awa, e neʻe mālie ia ma ke ala pōʻai i kahi manawa pōkole a ma hope e puʻunaue ʻia i nā awa ʻē aʻe. I ka wā o ka hoʻololi ʻana, ma muli o nā ʻano resonance o ka poloka dielectric a me ke ala paʻa o ke kaapuni, mālama ʻia ka ʻokoʻa hoʻololi o ka pae ma kahi o 90 degere, e loaʻa ana i ka hāʻawi mana pololei.
