【摘要】 设计了一款基于紧凑耦合的平面单极子手机天线,该天线由尺寸相当、紧凑耦合的平面单极子和寄生枝节构成,天线采用曲流技术可以获得更小的尺寸,主体部分下方镂空且结构上的简单、紧凑,利于整机设计.平面单极子和寄生枝节的基频及高阶共振模共同作用,使天线产生950 MHz和2 250 MHz两个谐振中心频率,覆盖了当今手机通信的GSM900/GSM1800/1900/UMTS以及LTE2300/2500等频段.更多还原

【Abstract】 A mobile phone antenna using a closed-coupling planar printed monopole for covering multi-bands of WWAN operation was presented. This antenna was formed by a monopole slot and a parasitic strip closed-coupled with similar size. The antenna used meander to get a smaller size. The space below the principal part was hollowed out,and it had a simple and closed structure,which was convenient for integrated design. Two resonance center frequencies 950 MHz and 2 250 MHz were generated by the base frequency and the higher resonant mode of both the planar monopole and the parasitic strip,which covered the main frequency of communication for mobile,such as GSM900 / GSM1800 /1900 / UMTS and LTE2300 /2500.更多还原
