This paper describes patch antenna design method of antenna high gain and broad bandwidth using cylindrical magneto material around feeding line. Strong current induction method applied combination to generate magnetic fields around feeding line for antenna high gain characteristic and principle of PIFA designed application for design of antenna broadband. In case of single CMM, gain increased 3.96 dB compare with the reference antenna gain however bandwidth characteristic not increased compare with the reference antenna. In case of dual CMM, gain improved about 10 dB compare with the reference antenna and -10 below bandwidth is 700 MHz(50 MHz~750 MHz) with this paper designed high gain characteristic.
