Munyaya dze microwave engineering, mashandiro e antenna chinhu chakakosha pakuona kushanda uye kushanda kwe wireless communication systems. Imwe yenyaya dzinonyanya kutaurwa nezvadzo ndeyekuti kuwedzera kwe antenna zvinoreva here kuti antenna iri nani. Kuti tipindure mubvunzo uyu, tinofanira kufunga nezvezvinhu zvakasiyana-siyana zvekugadzirwa kwe antenna, kusanganisira **Microwave Antenna** hunhu, **Antenna Bandwidth**, uye kuenzanisa pakati pe **AESA (Active Electronically Scanned Array)** uye **PESA (Passive Electronically Scanned Array)** tekinoroji. Pamusoro pezvo, tichaongorora basa re **1.70-2.60Antena yeGHZ Standard Gain Horn** mukunzwisisa kuwedzera uye zvazvinoreva.
Kunzwisisa Kuwana KweAntena
Kuwana maAntena chiratidzo chekuti antenna inotungamira kana kuti inosimbisa sei simba remafrequency eredhiyo (RF) munzira yakati. Inowanzo ratidzwa mumadecibel (dB) uye ibasa remagadzirirwo emwaranzi yeantenna. Antena ine gain yakawanda, senge **Antena yeNyanga yeGain Gain** Inoshanda mu **1.70-2.60 GHz**, inotarisa simba mugwara rakamanikana, izvo zvinogona kuvandudza zvakanyanya simba remasaini uye huwandu hwekutaurirana munzira yakati. Zvisinei, izvi hazvirevi hazvo kuti kuwedzera kwakanyanya kunogara kuri nani.

Basa reBandwidth yeAntenna
**Antenna Bandwidth** inoreva huwandu hwemafrequencies ayo antenna inogona kushanda zvinobudirira. Antenna ine high-gain inogona kunge iine bandwidth yakamanikana, zvichideredza kugona kwayo kutsigira wideband kana multi-frequency applications. Semuenzaniso, antenna ine high-gain horn yakagadzirirwa 2.0 GHz inogona kuomerwa kuchengetedza mashandiro pa1.70 GHz kana 2.60 GHz. Kusiyana neizvi, antenna ine low-gain ine bandwidth yakafara inogona kunge ichishanda zvakanyanya, zvichiita kuti ive yakakodzera kune maapplication anoda frequency agility.

Kutungamira uye Kufukidza
Maantenna ane simba guru, akadai sema parabolic reflectors kana ma antenna ehorn, anobudirira zvikuru mukutaurirana kwe point-to-point uko kuyera masaini kwakakosha. Zvisinei, mumamiriro ezvinhu anoda kufukidzwa kwese kwese, senge nhepfenyuro kana network dzenharembozha, hupamhi hwe beamwidth ye antenna ine simba guru hunogona kuva dambudziko. Semuenzaniso, apo ma antenna akawanda anotumira masaini kune imwe receiver, chiyero pakati pekuwana nekufukidzwa kwakakosha kuti kuve nechokwadi chekutaurirana kwakavimbika.

AESA vs. PESA: Kuwana uye Kuchinjika
Pakuenzanisa matekinoroji e **AESA** ne **PESA**, kuwana chinhu chimwe chezvinhu zvakawanda zvekufunga nezvazvo. Masisitimu eAESA, anoshandisa mamodule ekutumira/kugamuchira ega ega e antenna element, anopa kuwedzera kwekuwedzera, kutungamira kuri nani, uye kuvimbika kuri nani zvichienzaniswa nemasisitimu ePESA. Zvisinei, kuomarara kuri kuwedzera uye mutengo weAESA zvingasave zvakakodzera kune ese mashandisirwo. Masisitimu ePESA, kunyangwe asina kuchinjika zvakanyanya, achiri kukwanisa kupa kuwana kwakakwana kune akawanda mashandisirwo, zvichiita kuti ave mhinduro inoshanda zvakanyanya mune mamwe mamiriro ezvinhu.
Zvinhu Zvinofanira Kufungwa Nazvo
Antenna ye **1.70-2.60 GHz Standard Gain Horn** isarudzo yakakurumbira yekuyedza nekuyera muma microwave systems nekuda kwekushanda kwayo kunofungidzirwa uye kuwedzera kuri pakati nepakati. Zvisinei, kukodzera kwayo kunoenderana nezvinodiwa zveapplication. Semuenzaniso, mu radar system inoda kuwedzera kwakanyanya uye kudzora kwakaringana kwe beam, AESA ingasarudzwa. Kusiyana neizvi, wireless communication system ine zvinodiwa ne wideband inogona kukoshesa bandwidth pane kuwedzera.
Mhedziso
Kunyange hazvo kuwedzera kwesimba remasaini uye nzvimbo yaro, harisi iro chete rinoita kuti antenna ishande zvakanaka. Zvinhu zvakaita se **Antenna Bandwidth**, zvinodiwa pakufukidza, uye kuoma kwesystem zvinofanirawo kufungwa nezvazvo. Saizvozvowo, sarudzo pakati pe **AESA** ne **PESA** tekinoroji inoenderana nezvinodiwa zveapplication. Pakupedzisira, antenna "iri nani" ndiyo inonyatsoenderana nekushanda, mutengo, uye zvinodiwa zvesystem yainoiswa. Kuwedzera kwesimba kunobatsira muzviitiko zvakawanda, asi haisi chiratidzo cheantenna iri nani.
Kuti udzidze zvakawanda nezve antenna, ndapota shanyira:
