This article presents, optimizes, and measures a novel 3D electrically small antenna with dual-band. The optimized antenna works in 0.789 GHz and 1.183 GHz, showing simulated results similar to measured results, meeting the miniaturization requirements of modern wireless communication systems.
A novel 3D electrically small antenna with dual-band is presented, optimized, and measured in this article. The proposed antenna is composed of three circular split ring resonators and a vertical line, which has been obtained through rotating angles of three circular split ring resonators from the same direction to 260 degrees, 0 degrees, and 340 degrees. The optimized electrically small antenna is worked in 0.789 GHz and 1.183 GHz and has been verified that the simulated results are similar to the measured results. The design of the antenna structure conforms to the miniaturization in modern wireless communication systems.
