Yintoni i-Microstrip Antenna? Ulwakhiwo, uMgaqo wokusebenza kunye nezicelo

Isishwankathelo seMveliso kunye neTekhnoloji

I-antenna ye-microstrip yi-antenna ejikelezileyo eyenziwe yi-patch ekhupha imitha, i-substrate ye-dielectric, kunye ne-ground plane. I-patch idla ngokuprintwa kwelinye icala le-substrate, ngelixa i-ground plane ibekwe kwelinye icala. Olu lwakhiwo lwenza i-antenna ibe ncinci, ilula, kwaye ifaneleke ukufakwa kumaqonga athe tyaba okanye agobileyo kancinci.

Kwi-RF engineering esebenzayo, ii-antenna ze-microstrip zixatyiswa kuba zinokudityaniswa neesekethe ze-microwave, ii-arrays ezicwangcisiweyo, ii-radomes, kunye nee-compact system housings. Iimpawu zazo zemitha zinokulungiswa nge-patch geometry, izinto ze-substrate, indlela yokutya, ulungiselelo lwe-array, kunye noyilo lwe-mechanical.

Ulwakhiwo oluSisiseko lwe-Microstrip Antenna

I-antenna eqhelekileyo ye-microstrip ineeleya ezintathu eziphambili. I-patch yesinyithi ephezulu isebenza njenge-element ekhupha imitha. I-substrate ye-dielectric ixhasa i-patch kwaye ichaphazela i-bandwidth, ukusebenza kakuhle, kunye nobukhulu. I-plane esezantsi yomhlaba inceda ukuchaza indlela esebenza ngayo imitha kwaye yahlula i-antenna kumphezulu wokufakelwa.

Isebenza njani i-Antenna ye-Microstrip?

Xa amandla e-RF efakwa kwi-patch, kwakheka intsimi ye-electromagnetic phakathi kwe-patch kunye nomhlaba. Imitha yelanga yenzeka kakhulu kufutshane nemiphetho ye-patch, apho intsimi ye-fringing ifikelela kwindawo ejikelezileyo.

I-frequency yokusebenza inxulumene kakhulu nobukhulu be-patch, i-substrate dielectric constant, kunye nobukhulu be-substrate. Kwi-patch engunxande, ubude be-resonant buqhele ukunxulumana nesiqingatha sobude be-wavelength obukhokelwayo ngaphakathi kwe-substrate.

Kwimizobo yokwenyani, ubukhulu bokugqibela kufuneka buphuculwe kuba umthwalo we-dielectric, indawo yokutya, indawo yokuhlala, izinto ze-radome, kunye nezakhiwo zesinyithi ezikufutshane zonke zinokuchaphazela ukusebenza okulinganisiweyo.
