Antenna transducers hote hai. Yeh same frequency pr radio frequency electric current ko electromegnetic (EM) wave mein change kr deta hai. in dono wave ki frequency same hoti hai. Antenna ko ariel bhi kehte hai. Antenna, Conducting Material ka piece hota hai jo wire, rod or radiator hota hai. yeh electromagetic wave ke liye sensors ki taraf kaam krta hai.
Basic Elements of Antenna –
(i) Alternative Current Elements (ii) Short Dipole (iii) Short Monopole (iv) Half Wave Dipole (v) Quater Wave Dipole
