KanyangaKuwana antenna chinhu chakakosha mumasisitimu ekutaurirana asina waya, sezvo ichisarudza kugona kweantenna kutungamira kana kuomerera simba remafrequency eredhiyo munzira yakatarwa. Kuwana antenna yakawanda kunovandudza simba remasaini, kunowedzera huwandu hwekutaurirana, uye kunowedzera mashandiro ehurongwa hwese. Chinyorwa chino chinoongorora nzira dzinoshanda dzekuwedzera kuwana antenna, tichitarisa pamisimboti yekugadzira, matekiniki ekugadzirisa, uye matekinoroji epamusoro.
1. Gadzirisa Dhizaini yeAntena
Kubudirira kweantenna kwakabatana zvikuru nekugadzirwa kwayo. Imwe yenzira dzinoshanda dzekuwedzera kuwedzera ndeyekushandisa antenna inotungamira, senge Yagi-Uda, parabolic reflector, kana patch antenna, iyo inotarisa simba munzira yakati pane kuriburitsa zvakaenzana munzira dzese. Semuenzaniso, parabolic reflector antennas dzinowana kuwedzera kwakanyanya nekuisa masaini panzvimbo yepakati, zvichiita kuti ave akakodzera kutaurirana kure.
2. Wedzera Saizi yeAntena
Kuwana maAntena kunoenderana nekuvhura kwayo kunoshanda, uko kwakabatana zvakananga nehukuru hwayo hwepanyama. MaAntena makuru anogona kubata kana kuburitsa simba rakawanda, zvichikonzera kuwedzera kukuru. Semuenzaniso, maAntena edhishi ane dhayamita yakakura anopa kuwedzera kukuru nekuda kwekuwedzera kwenzvimbo yawo yepamusoro. Zvisinei, nzira iyi inoganhurirwa nezvirambidzo zvinoshanda zvakaita senzvimbo nemari.
3. ShandisaMagadzirirwo eAntena
MaAntenna arrays ane maantenna akawanda akarongwa nenzira yakatarwa. Nekubatanidza masaini kubva kuzvinhu izvi, array inogona kuwana gain uye directionivity yakakwira. MaAntenna arrays ane phased, semuenzaniso, anoshandisa nzira dzekuchinja phase kuti atungamirire beam nemagetsi, zvichipa gain yakakwira uye flexible mu directionality.

4. Kuvandudza Kushanda Kwechikafu Nesimba
Sisitimu yekudyisa, iyo inofambisa simba pakati pemuchina wekutumira/kugamuchira neantenna, inoita basa rakakosha pakuona kuwedzera kwesimba. Kushandisa zvinhu zvinoderedza kurasikirwa uye kugadzirisa network yekudyisa kunogona kuderedza kurasikirwa kwesimba uye kuvandudza kushanda zvakanaka. Semuenzaniso, tambo dze coaxial dzine kuderera kwekurerutswa kana ma waveguide feeds dzinogona kuwedzera kushanda.
5. Deredza Kurasikirwa
Kurasikirwa muhurongwa hweantenna, zvakaita sekurasikirwa kwe resistive, kurasikirwa kwe dielectric, uye kusawirirana kwe impedance, kunogona kuderedza zvakanyanya gain. Kushandisa zvinhu zvine conductivity yepamusoro (semuenzaniso, mhangura kana aruminiyamu) pakuvaka antenna uye zvinhu zvine dielectric zvishoma kurasikirwa kune substrates kunogona kuderedza kurasikirwa uku. Pamusoro pezvo, kuve nechokwadi chekuti impedance yakabatana zvakanaka pakati peantenna ne transmission line inowedzera kutamiswa kwesimba uye inowedzera gain.
6. Shandisa Vagadziri veReflectors neVatungamiriri
Mumaantenna anotungamira senge maantenna eYagi-Uda, ma reflector nemadirector anoshandiswa kuwedzera gain. Ma reflector anoiswa kumashure kwechinhu chinopenya kuti atungamire simba mberi, nepo madirector akaiswa pamberi kuti atarise mwenje mberi. Kuisa nzvimbo nehukuru hwakanaka hwezvinhu izvi kunogona kuvandudza gain nekutungamira zvakanyanya.
Mhedziso
Kuwedzera kuwedzera kwe antenna kunosanganisira kusanganiswa kwekugadzira kwakanyatsonaka, kusarudzwa kwezvinhu, uye matekiniki epamusoro. Nekugadzirisa chimiro che antenna, kuderedza kurasikirwa, uye kushandisa matekiniki akadai se antenna arrays uye beamforming, zvinokwanisika kuwana kuvandudzwa kukuru mukuwedzera uye kushanda kwese kwesystem. Kuvandudzwa uku kwakakosha kune mashandisirwo akasiyana kubva pakutaurirana kusina waya kusvika kune radar uye satellite systems.
Kuti udzidze zvakawanda nezve antenna, ndapota shanyira:
