摘要： 提出一款应用于第五代金属边框智能手机的高隔离度两天线模块。基于一个蚀刻在地板上的T形缝隙，通过合理地设计一个耦合馈电环天线和一个耦合馈电缝隙天线，实现了一款紧凑的两天线模块。尽管耦合馈电环天线和耦合馈电缝隙天线共口径，两者之间的隔离度高于30 dB。随后，通过集成4个两天线模块，实现了一款8×8多入多出系统。该系统实测互耦和包络相关系数分别小于−18.5 dB和0.02。

摘要： Though they reduce microorganism growth, current hospital disinfectants also damage many of today’s modern electronic devices such as tablets and smartphones. Herein, the efficacy of a new chlorhexidine digluconate gel (CDG) was tested as a disinfectant for mobile and electronic devices in a clinical environment. Specifically, , , and methicillin resistant were used to infect the screen of eight smartphones. The CDG was prepared at concentrations of 2%, 4% and 6%, and tested on paper disks infected with these bacteria before being tested on the smartphones. The devices were disinfected with the CDG gel (4%) at two times: immediately and after 5 min of the bacterial contamination. In all cases, the CDG gel eliminated 100% of gram-positive and gram-negative microorganisms compared to the control (without any agent). In addition, the gel did not damage the smartphones. Therefore, our study suggests that the CDG gel may be applied to disinfect a wide range of electronic devices for health care professionals in the hospital environment.
