碩士 === 義守大學 === 電子工程學系 === 102 === Cell phone antennas with light, thin, short and small are widely adopted in wireless network communication. The frequency bands included are the GSM 900/1800 (2G), UMTS 2100 (3G), as well as the evolving LTE 700/900/1800/2100/2300/2600 (4G). This paper presents the miniaturized antennas applicable for LTE, in which the characteristic impedance of microstrip is 50Ω. The proposed antenna was printed on FR4 substrates, and the size is 125×60×0.8mm3. This antenna is a dual-frequency band, and is combination of monopole antenna and coupled PIFA antenna. The design frequency bands are for LTE 0.9/1.8/2.3/2.6GHz. The simulator HFSS is employed for simulation and results show that 0.9/1.8/2.3/2.6GHz are included in the band.
