为多标准多功能移动的手机和便携式计算机开发了一种双谐振天线配置。在便携式通信设备中，仅两个宽带谐振天线就可以覆盖大部分LTE频谱。在不使用任何匹配或调谐电路的情况下，每个天线可以覆盖的带宽超过70%，效率达到80%。因此，它们的双重配置能够覆盖除了现有的2G和3G频带之外的多达39个LTE（4G）频带。设计了2 × 2 MIMO结构，使主天线和分集天线之间的隔离度最大，相关系数最小。
A dual resonant antenna configuration is developed for multistandard multifunction mobile handsets and portable computers. Only two wideband resonant antennas can cover most of the LTE spectrums in portable communication equipment. The bandwidth that can be covered by each antenna exceeds 70% without using any matching or tuning circuits, with efficiencies that reach 80%. Thus, a dual configuration of them is capable of covering up to 39 LTE (4G) bands besides the existing 2G and 3G bands. 2 × 2 MIMO configurations have been also developed for the two wideband antennas with a maximum isolation and a minimum correlation coefficient between the primary and the diversity antennas.
