ʻAntenna Microstrip 22dBi Typ. Gain, 25.5-27 GHz Frequency Range RM-MA25527-22

ʻO ka antenna microstrip, i ʻike ʻia hoʻi he antenna patch, he ʻano antenna ia i ʻike ʻia no kona ʻano haʻahaʻa, māmā, maʻalahi o ka hana ʻana, a me ke kumukūʻai haʻahaʻa. ʻO kona ʻano kumu he ʻekolu papa: kahi ʻāpana metala e hoʻomālamalama ana, kahi substrate dielectric, a me kahi mokulele honua metala.

Hoʻokumu ʻia kāna kumu hana ma ka resonance. Ke hoʻonāukiuki ʻia ka ʻāpana e kahi hōʻailona hānai, kani kahi kahua electromagnetic ma waena o ka ʻāpana a me ka mokulele honua. Loaʻa ka radiation mai nā ʻaoʻao hāmama ʻelua (ma kahi o ka hapalua o ka nalu kaʻawale) o ka ʻāpana, e hana ana i kahi kukuna kuhikuhi.

ʻO nā pono nui o kēia antenna ʻo ia kona ʻano pālahalaha, ka maʻalahi o ka hoʻohui ʻana i nā papa kaapuni, a me ke kūpono no ka hoʻokumu ʻana i nā arrays a i ʻole ka hoʻokō ʻana i ka polarization circular. Eia nō naʻe, ʻo kona mau hemahema nui he bandwidth haiki, ka loaʻa haʻahaʻa a waena, a me ka palena o ka mana lawelawe mana. Hoʻohana nui ʻia nā antennas Microstrip i nā ʻōnaehana uea ʻole hou, e like me nā kelepona paʻalima, nā polokalamu GPS, nā mea hoʻohele Wi-Fi, a me nā tag RFID.
