摘要：

A metamaterial resonator loaded small dipole antenna placed above the electromagnetic bandgap (EBG) surface is proposed. Two split ring resonators (SRRs) are loaded to the dipole. The dipole antenna, the SRRs, and the EBG are integrated in one dielectric using Low Temperature Co-fired Ceramic (LTCC) technique. The simulation results demonstrate that, by loading the SRR structure, a low profile and very small dipole (less than 0.15 lambda in length) antenna over an EBG can have a broad bandwidth. A bandwidth of 10% at 1.93 GHz is achieved. The simulated gain is greater than 6.1 dB and efficiency is 90%. Few EBG cells used in the present design reduce the overall size of the antenna structure. The volume of the antenna including the EBG structure is 0.51 lambda x0.42 lambda x0.05 lambda.
