[Abstract]:Based on the rapid development of wireless communication system, aiming at the urgent need of miniaturization, high performance and multi-band development of the next generation smartphone terminal antenna, based on the theory of compound left and right hand transmission line, A new smart phone terminal antenna covering LTE band is designed. The miniaturization and high performance design of the antenna are realized by applying the zero-order resonance principle to load the equivalent left-handed capacitance, the left-handed inductance structure and the introduction of ground loop current in the antenna design. The working band coverage LTE747/GSM850/900/DCS1800/PCS1900/UMTS/LTE2300/2600, of the antenna has good radiation characteristics, high radiation efficiency and gain, and can meet the design requirements of LTE intelligent mobile terminal. In this paper, the working characteristics of the antenna are analyzed in detail, and the machining measurement is carried out at the same time. The measured results show that the fabricated antenna is in good agreement with the simulation results, and the zero-order resonant supermaterial antenna has the advantages of miniaturization and high performance.
