Case study: Cowin antenna's 4G waterproof rod antenna inoshanda nemakambani ephotovoltaic kuchinja nharaunda, zvichiita kuti denga rive neblue uye mvura ijeke.
Mutengi
Iyo yepamusoro 500 yepasirese kambani inobata ibhizinesi rakasiyana-siyana repamusoro-soro uye rekugadzira bhizinesi revagadziri ve inverter uye simba rekuchengetedza system.
Antenna kuita zvinodiwa:
Iyo antenna ine basa rekudzivirira mvura uye UV kudzivirira, uye inokwanisa kusangana nechiratidzo chekugamuchira kwevatatu makuru anoshanda panguva imwe chete.
Dambudziko:
Zvinhu zvisina kugadzikana zvechiratidzo chemushandisi munzvimbo dziri kure zvinokonzeresa kukanganiswa kwechiratidzo, izvo zvinoedza kuita kweantenna. Panguva imwecheteyo, nzvimbo yakaoma ye photovoltaics inounzawo mamwe matambudziko akasiyana-siyana, akadai sepamusoro uye kuderera kwekushisa kwekushisa uye kuzununguka, saka zvakakosha kukudziridza yakarurama A mhinduro inoreva kuputsa miganhu yehutano uye yemuviri.
Solution:
1.698-960 / 1710-2700MHz yakazara-bhendi yekuvhara, yakakura-saizi antennas inogona kupa yakakura bandwidth uye nepamusoro-soro, inokanganiswa nehukuru hwechigadzirwa chakamiswa, kudzvanya uye tune iro renji zvinoenderana neinodiwa saizi yeantenna, kazhinji inoda Yakasiyana siyana. yekuchinja kwesimba kuti uwane mafambiro ekufambisa, saka akawanda tuning zvinhu uye/kana kuwanda kwehuwandu hwekutuniya hunowanzodiwa. Kune izvi, mainjiniya anowedzera resonance poindi yeantenna mutsara uye anofananidza dunhu remidziyo.
2. Kufuridzirwa nehukuru, mainjiniya anosarudza matanda emhangura yepamusoro uye maviri-sided circuit boards kuti agadzirise resonant frequency, uye muedzo wekamuri yerima unosvika kusvika ku3DB kuwana uye 60% kunyatsoshanda.
3. A 2MM gobvu isina mvura silicone gasket inowedzerwa pakubatana pakati peantenna uye chigadziro chekugadzirisa kaviri kuti chimiro chemukati chechigadzirwa uye antenna hachikanganisike nekunaya kwemvura.
4. UV agent inowedzerwa pakuumbwa kwegoko repurasitiki, uye hapana kukanganiswa nekutsemuka mushure meyepamusoro uye yakaderera tembiricha cycle bvunzo ye - 40 ˚C ~ + 80 ˚C kwemaawa makumi masere.
5. Hukuru hwese hwekupedzisira antenna musanganiswa ndeye 90 * 10MM kureba, uye yakapfuura bvunzo chaiyo yemutengi uye kugamuchirwa.
Mabhenefiti ehupfumi:
Mutengi akabudirira kuburitsa chigadzirwa kumusika uye akawana kutengesa kwe300,000 units.
