Aaj kal ke gadgets itne advanced ho gaye hain ki unmein jo technology use hoti hai, woh kai baar humein dikhti bhi nahi hai. Waise hi ek cheez hai built-in antenna. Bohot log iske baare mein sochte bhi nahi hain, aur agar sochte hain toh ek common sawal hota hai – “Yeh built-in antenna hota kahan hai?”
Pehle ke zamane mein radio aur TV ke bade-bade antenna dikhte the, jo tower jaisa lagta tha. Lekin aaj ke smartphones, laptops, smart TVs aur smartwatches mein yeh antenna kahin chhupa hota hai. Humein pata bhi nahi chalta ki hum jis device ka use kar rahe hain, usme ek built-in antenna silently kaam kar raha hai aur humein best signal de raha hai.
Agar aap apna phone dekho, toh kahin koi bada antenna dikhai nahi dega. Kyunki manufacturers ne usse internal design ka ek part bana diya hai. Usually, yeh frame ke andar ya back panel ke kisi kone mein hota hai, taaki signal reception best rahe. Isliye kabhi kabhi agar aap apna phone galat tareeke se pakad lete ho, toh network weak ho sakta hai, kyunki aap antenna ko block kar dete ho.
Laptops aur smart TVs mein bhi same concept hota hai. Antenna andar hi fitted hota hai, aur woh device ke design ke hisaab se body ke kisi kone ya screen ke peeche hota hai. Smartwatches mein bhi ek chhota sa built-in antenna hota hai jo GPS, WiFi aur Bluetooth ke signals ko pakadta hai.
Toh agar aapko bhi kabhi laga ki “built-in antenna? Yeh toh dikhta hi nahi!”, toh tension mat lo. Woh wahi hai, chhupa hua, bina kisi shor-sharabe ke kaam karta hua, taaki aapka network aur connectivity perfect rahe!
