Kune akawanda maBluetooth maapplication anoda kushanda kwepamusoro uye kureba kana saizi diki, vanogadzira vangada kushandisa maBluetooth module anotsigira ekunze antenna muPCBA yavo. Nekuti kazhinji ndiyo inonyanya kushanda nzira yekuita kuti huwandu hwekutumira hweBluetooth module hurebe uye kuita kuti saizi yePCBA ive diki, unenge uchibvisa chikamu cheiyo antenna uye kushandisa antenna yekunze panzvimbo.
Asi ndeipi ingave nzira yakanakisa yekumisikidza antenna yekunze?
Kutora maviri-layer PCBA semuenzaniso:
1. Ita shuwa kuti zvikamu zviri pabhodhi zvakarongeka.
2. Iva nechokwadi chokuti pane nzvimbo yakakura yendarira yepasi uye nhamba yakakwana yekupfuura nemakomba.
3. Iyo RF microstrip line inoda kuita 50-ohm impedance, iyo referensi layer ndiyo yechipiri layer.
4. Chengetedza π-mhando inoenderana nedunhu, uye ita kuti ive pedyo nechigaro cheRF. Kuburikidza nedebugging yedunhu rinoenderana, ita shuwa kuti antenna iri mune yakanakisa mamiriro.
5. Ita shuwa kuti RF microstrip line yakakomberedzwa newaya yepasi (shield).
6. Usaisa mutsara we data, mutsara wewachi, nezvimwewo pasi pe module, uye chengetedza pasi se ndege huru uye yakazara pasi.
7.Inosanganiswa nedhiyabhorosi dhiyagiramu yechikamu chechipiri, inogona kuonekwa kuti RF microstrip line ine-dimensionally mitatu yakakomberedzwa nevhu (nhovo).
Mukupedzisa, ita shuwa kuti antenna yekunze yakaiswa panzvimbo chaiyo, uye ita shuwa kuti antenna haina kukanganiswa kubva kune mamwe mitsara pabhodhi.
Iwe unofanirwa kuve uine chero mibvunzo panguva yekumisikidza antenna, usazeza kubata Feasycom izvozvi!
