Abstract: A Vivaldi antenna with circular patch and complementary split ring resonator (CSRR) slots etched has presented in this paper. The shape of the patch, defected ground structure, slots and feeding are considered to enhance the gain and bandwidth of proposed antenna. The triple frequency band operation over 5 GHz to 15 GHz frequency range with the return loss of -27.46, -11.23, and -13.61 dB at three operating frequencies 7.28GHz, 11.7 GHz and 14.44 GHz respectively are observed for the proposed design. The proposed Vivaldi antenna with slots can be used for satellite broadcasting applications.
