antenna ,is it act like an exitation source for loop antenna to generate oscillations.plz answer it
An inductive coupling link/loop can be used with a loop antenna. This works in the same way as a transformer, with the inductive link as the primary (for transmitting), but at the particular radio frequency. A loop antenna often represents some sort of resonant circuit, and this can be combined with the inductive link coupling to match the antenna impedance to the transmission line and transmitter impedances. With other types of antenna an inductor and/or capacitor arrangement (an LC network) may be used for matching the antenna impedance to the lines. The actual values and conficuration depends on the specific antenna. For example, teh model of a vertical quarter wave antenna is a small capacitor in series with the radiation resistance. By adding a series inductor the capacitance can be made to resonate, maximising the current in the radiation resistance.
At t0, swap closed and a means got here across the inductor. So that's form of a Alternating present day for a 2nd. That alternating present day makes inductor to act like in AC circuit. that has effects on shrink consistently after t+ time because of the fact of dc voltage. there'll a opposing electromagnetic field interior the inductor via surprising voltage. which will supply up present day to bypass interior the direction of the inductor
