Nowadays mobile usage is the essential need of humans. To provide the mobile network services, the Telecommunication companies propose the installation of Base Transceiver Station over large populated and industrial areas. The radiations emit from these BTS may give rise to various electromagnetic and ecological compatibility issues [1]. The radiation power of these BTS is up to 5-10 KiloWatts (up to 320-350 W per channel), which can be detrimental for the human beings, if they are installed in populated areas. The purpose of this paper is to reduce the transmission power of the BTS which is possible through the usage of Self-phased array antenna. Self-phasing array antenna through the use of pilot carrier in Telecommunication systems can degrade the Tx upto10-20dB
