Pankhani ya uinjiniya wa microwave, magwiridwe antchito a antenna ndi chinthu chofunikira kwambiri pakuzindikira bwino komanso kuchita bwino kwa machitidwe olumikizirana opanda zingwe. Imodzi mwamitu yomwe imakambitsirana kwambiri ndi yakuti ngati kupindula kwakukulu kumatanthawuza mlongoti wabwinoko. Kuti tiyankhe funsoli, tiyenera kuganizira mbali zosiyanasiyana za kamangidwe ka mlongoti, kuphatikizapo maonekedwe a **Microwave Antenna**, **Antenna Bandwidth**, ndi kuyerekeza kwa **AESA (Active Electronically Scanned Array)** ndi **PESA (Passive Electronically Scanned Array)** matekinoloje. Kuphatikiza apo, tiwona ntchito ya **1.70-2.60GHz Standard Gain Horn Antenna** pakumvetsetsa phindu ndi zotsatira zake.
Kumvetsetsa Kupindula kwa Antenna
Kupindula kwa mlongoti ndi muyeso wa momwe mlongoti umawongolera kapena kuyika mphamvu ya ma radio frequency (RF) mbali ina yake. Nthawi zambiri imawonetsedwa mu ma decibel (dB) ndipo ndi ntchito yama radiation ya tinyanga. Mlongoti wolemera kwambiri, monga **Mlongoti wa Horn wa Standard Gain** ikugwira ntchito mu **1.70-2.60 GHz** range, imayang'ana mphamvu mu mtengo wopapatiza, womwe ukhoza kupititsa patsogolo mphamvu ya ma sigino ndi njira yolankhulirana mbali inayake. Komabe, izi sizikutanthauza kuti kupindula kwakukulu nthawi zonse kumakhala bwinoko.

Udindo wa Bandwidth ya Antenna
**Bandwidth ya mlongoti** imatanthawuza kusiyanasiyana kwa ma frequency omwe mlongoti umatha kugwira ntchito bwino. Mlongoti wopindula kwambiri ukhoza kukhala ndi bandwidth yopapatiza, kuchepetsa kuthekera kwake kuthandizira ma wideband kapena ma multi-frequency applications. Mwachitsanzo, mlongoti wa nyanga yopindula kwambiri wokometsedwa kwa 2.0 GHz akhoza kuvutika kuti apitirize kugwira ntchito pa 1.70 GHz kapena 2.60 GHz. Mosiyana ndi izi, mlongoti wopeza pang'ono wokhala ndi bandwidth yotakata ukhoza kukhala wosunthika, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito zomwe zimafuna kusinthasintha pafupipafupi.

Directionality ndi Kufalikira
Ma antenna olemera kwambiri, monga ma parabolic reflectors kapena ma antennas a horn, amapambana pamakina olankhulirana poyambira ndi nsonga pomwe kuyika kwa ma siginecha ndikofunikira. Komabe, pazochitika zomwe zimafuna kufalikira kwa njira zonse, monga kuwulutsa kapena ma network am'manja, kupendekera kwakukulu kwa mlongoti kumatha kukhala kosokoneza. Mwachitsanzo, pamene tinyanga zambiri zimatumizira zizindikiro kwa wolandira m'modzi, kulinganiza pakati pa kupindula ndi kuphimba ndikofunikira kuti zitsimikizire kulankhulana kodalirika.

AESA vs. PESA: Kupindula ndi Kusinthasintha
Poyerekeza matekinoloje a **AESA** ndi **PESA**, kupindula ndi chimodzi mwazinthu zambiri zomwe muyenera kuziganizira. Machitidwe a AESA, omwe amagwiritsa ntchito ma modules otumizira / kulandira pamtundu uliwonse wa antenna, amapereka phindu lalikulu, chiwongolero chabwino cha matabwa, ndi kudalirika kwabwino poyerekeza ndi machitidwe a PESA. Komabe, kuchuluka kwazovuta komanso mtengo wa AESA sizingakhale zomveka pazofunsira zonse. Machitidwe a PESA, ngakhale osasinthasintha, angaperekebe phindu lokwanira pazochitika zambiri zogwiritsira ntchito, kuwapanga kukhala njira yotsika mtengo pazochitika zina.
Mfundo Zothandiza
**1.70-2.60 GHz Standard Gain Horn Antenna** ndi chisankho chodziwika bwino pakuyesa ndi kuyeza mu makina a microwave chifukwa cha magwiridwe ake odziwikiratu komanso kupindula pang'ono. Komabe, kuyenerera kwake kumadalira zofunikira zenizeni za ntchitoyo. Mwachitsanzo, pamakina a radar omwe amafunikira kupindula kwakukulu komanso kuwongolera bwino kwamitengo, AESA ingakhale yabwino. Mosiyana ndi izi, makina olumikizirana opanda zingwe okhala ndi zofunikira za wideband amatha kuika patsogolo bandwidth kuposa phindu.
Mapeto
Ngakhale kupindula kwakukulu kumatha kupititsa patsogolo mphamvu ya ma siginecha ndi kuchuluka kwake, sizomwe zimawonetsa momwe tinyanga zimagwirira ntchito. Zinthu monga ** Antenna Bandwidth **, zofunikira pakuphimba, ndi zovuta zamakina ziyeneranso kuganiziridwa. Momwemonso, kusankha pakati pa matekinoloje a **AESA** ndi **PESA** kumatengera zosowa zenizeni za pulogalamuyo. Pamapeto pake, mlongoti "wabwino" ndi womwe umakwaniritsa bwino magwiridwe antchito, mtengo wake, komanso magwiridwe antchito a dongosolo lomwe wayikidwamo. Kupindula kwakukulu kumakhala kopindulitsa nthawi zambiri, koma si chizindikiro chapadziko lonse cha mlongoti wabwino.
