Ma ke ʻano he ʻano hānai o nā antenna waveguide, ʻo ka hoʻolālā ʻana o ka microstrip i ka waveguide e hana koʻikoʻi i ka hoʻoili ʻana o ka ikehu. ʻO ka microstrip kuʻuna i ke kumu alakaʻi nalu penei. Hoʻokomo ʻia kahi ʻimi e lawe ana i kahi substrate dielectric a hānai ʻia e kahi laina microstrip i loko o ka ʻāpana o ka paia ākea o ka ʻaoʻao hawewe rectangular. ʻO ka mamao ma waena o ka probe a me ka paia pōkole ma ka hope o ka nalu e pili ana i ʻehā mau manawa o ka lōʻihi o ka hawewe hana. hookahi hapa. Ma lalo o ka manaʻo o ke koho ʻana i ka substrate dielectric, pili ka reactance o ka probe i ka nui o ka laina microstrip, a ʻo ka reactance o ka hawewe pōkole pōkole e pili ana i ke kūlana o ka pā pōkole. Hoʻopili piha ʻia kēia mau ʻāpana e hoʻokō i ka hoʻohālikelike ʻana i ka impedance o nā resistors maʻemaʻe a hōʻemi i ka lawe ʻana i ka ikehu.

ʻO Microstrip i ka hoʻolālā alakaʻi nalu i nā manaʻo like ʻole

Nā huahana RFMISO Microstrip Antenna series:

RM-MA25527-22

RM-MA425435-22

E like me nā manaʻo hoʻolālā i hāʻawi ʻia ma ka palapala, e hoʻolālā i kahi alakaʻi nalu i ka microstrip converter me ka bandwidth hana o 40 ~ 80GHz. ʻO nā hiʻohiʻona mai nā hiʻohiʻona like ʻole e like me kēia. Ma ke ʻano he laʻana maʻamau, hoʻohana ʻia kahi alakaʻi nalu maʻamau. Hoʻokumu ʻia ka mānoanoa a me ka dielectric mau o ka mea dielectric i hoʻoponopono ʻia nā ʻano impedance o ka microstrip probe.
Mea kumu: dielectric mau 3.0, mānoanoa 0.127mm
Nui alakaʻi nalu a*b: 3.92mm*1.96mm
ʻO 1.08 * 0.268 ka nui o ka āwaha ma ka pā ākea, a ʻo ka mamao mai ka pā pōkole pōkole he 0.98. E ʻike i ke kiʻi no nā ʻāpana S a me nā hiʻohiʻona impedance.

Nānā mua

Nānā hope

Nā palena S: 40G-80G

ʻO ka poho o ka hoʻokomo ʻana i ka laulā passband ma lalo o 1.5dB.

Nā hiʻohiʻona impedance awa

Zref1: ʻO ka impedance hoʻokomo o ka laina microstrip ʻo 50 ohms, Zref1: ʻO ka impedance hawewe i loko o ke alakaʻi nalu ma kahi o 377.5 ohms;

ʻO nā ʻāpana hiki ke hoʻopaneʻe ʻia: ka hohonu hoʻokomo ʻana i ka ʻimi D, ka nui W*L a me ka lōʻihi o ke āpau mai ka paia pōkole. E like me ka helu kikowaena waena 45G, ʻo ka dielectric mau ʻo 3.0, ʻo ka hawewe like he 3.949mm, a ʻo ka lōʻihi o ka hawewe like he 0.96mm. Ke kokoke i ka hoʻohālikelike kūʻokoʻa maʻemaʻe, e hana ana ke alakaʻi nalu ma ke ʻano nui TE10, e like me ka hōʻike ʻana ma ka puʻunaue kahua uila ma ke kiʻi ma lalo nei.
