What happens to current when antenna transmits and receive signal at the same time?

hi want to know that if an antena transmit and receive signal at same time ( full duplex) , then what is happening in the matel of antenna i mean if waves are received and send same time then the current also going and coming in same pasth at same time ?

but wat happen to current ? i know that there are two chanal having different frequency
but wat happen when a wave reciecve and send on same place of attena at same ttime ? how current behave ?[/b]

Full-duplex use ALWAYS different frequencies for RX and TX, otherwise the transmitter will jam the receiver.
So, the RX and TX antenna currents will have different frequencies and probably different paths.

Half-duplex systems or some TDMA systems could use the same frequency for RX and TX, but at different times, so the RX and TX antenna currents will never interact one to each other.
