Abstract :
The main problems in phased array antenna are mutual coupling and ground effects that destroys the designed radiation pattern. In this paper these undesired effects is compensated over 5 dB for mutual coupling effect and about 10 dB for both mutual coupling and ground effects in wide frequency band 30-88 MHz.
