ʻO Microstrip Antenna 22dBi Type. Loaʻa, 25.5-27 GHz Laulā ʻauwaʻa RM-MA25527-22

ʻO kahi antenna microstrip, ʻike ʻia hoʻi he antenna patch, he ʻano antenna i ʻike ʻia no kona ʻano haʻahaʻa, ke kaumaha māmā, ka maʻalahi o ka hana ʻana, a me ke kumu kūʻai haʻahaʻa. ʻO kona ʻano kumu he ʻekolu mau papa: kahi pākuʻi metala, kahi substrate dielectric, a me kahi mokulele honua metala.

Hoʻokumu ʻia kāna kumu hana ma ka resonance. Ke hoʻohauʻoli ʻia ka pāpaʻi e kahi hōʻailona hānai, hoʻāla ʻia kahi kahua electromagnetic ma waena o ka patch a me ka mokulele honua. Loaʻa mua ʻia ka hoʻoheheʻe ʻana mai nā ʻaoʻao hāmama ʻelua (i hoʻokaʻawale ʻia ma kahi o ka hapalua o ka lōʻihi hawewe) o ka pā, e hana ana i ke kukui kuhikuhi.

ʻO nā pōmaikaʻi nui o kēia antenna ʻo kāna ʻaoʻao pālahalaha, maʻalahi o ka hoʻohui ʻana i nā papa kaapuni, a me ke kūpono no ka hana ʻana i nā arrays a i ʻole ka hoʻokō ʻana i ka polarization circular. Eia nō naʻe, ʻo kāna mau drawbacks he haiki liʻiliʻi, haʻahaʻa a haʻahaʻa i ka loaʻa ʻana, a me ka hiki ke mālama i ka mana. Hoʻohana nui ʻia nā antenna Microstrip i nā ʻōnaehana uila hou, e like me nā kelepona paʻalima, nā polokalamu GPS, nā mea ala Wi-Fi, a me nā hōʻailona RFID.
