Abstract:

This paper describes the design and analysis of circular complementary split ring resonator (CSRR) with microstrip linear array antennas. Several improvements that result from the introduction of linear array with circular CSRR such as higher gain, wider bandwidth, and high antenna efficiency. The performance of the antenna is presented using the simulation results obtained from Computer Simulation Technology software. The results show an increase of gain with the increase of element in the linear array from 13.3dB for 1x4 linear array MPA to 16.4dB for 1x8 linear array MPA, 10.6dB for 1x4 linear array MPA with circular CSRR to 12.3dB for 1x8 linear array MPA with circular CSRR. Plus, the total efficiency of antenna ranges from 89% to 91%. The method proposed in this paper can be used to develop a simple and compact dual band millimeter wave antenna.
